Introduction

Planning of urban land use is a process of allocating of suitable land parcels for different kind of uses as per

requirement/need for the society. Remote sensing and GIS technology was demonstrated for urban planning in

India with the preparation of GIS database for DMA (Delhi Metropolitan Authority) and pilot project of BMR

(Bombay Metropolitan Region) under NRIS was taken up in the year of around 1990 by Space Applications

Centre, Ahmedabad. The multivariate index approach in GIS was employed to derive various planning

scenarios. Subsequently the similar methodology was adopted for the cities of Ahmedabad (AUDA -

Ahmedabad Urban Development Authority), Indore, Pimpri Chinchvad Municipal Corporation, Pune (PCMC),

Bhopal and Perambalur. The experience gained during the above projects and other studies were lead to

formulate the programme called NUIS at national level.

As all urban settlements subsist on land, it is land that constitutes the single most important component of the

total environment. The condition of the land on which the settlement is built, its effect on the surrounding lands

and the changes, which occur in land use, would determine, whether this single most important resource has

been used wisely by mankind or not. The studies on various human settlement analysis shows that the rapid and

haphazard growth of urban sprawl and increasing population pressure is resulting in deterioration of infrastruc-

ture facilities, loss of productive agricultural lands, green open spaces, loss of surface water bodies, depletion of

ground water aquifer zones, air pollution, water contamination, health hazards and many micro-climatic

changes. Therefore, the environmentally compatible urban planning must begin with a comprehensive look on

the use of land. It is in this regard, the development plan or Master Plan of the city is revised every 10 years to

take care of the population pressure and provide better quality of life in the city and its environs.

In the preparation of a environmentally compatible urban development plan, it is a prerequisite to understand

linkages and interactions that exist between different components of the urban environment. Secondly, the data

collected on different aspects of the urban environment has to be translated into useful information for the

purpose of urban development. Thirdly, there is also a need to aggregate this information according to

administrative/natural and hierarchical units. Basic caveat for this is the availability of systematic, detailed,

reliable, timely and accurate information on various facets of urban environment. Experiences gained so far

show certain shortcomings in regard to acquisition of statistics, processing, generation of graphic outputs and

their storing in the existing conventional system. Such a lacuna impedes efficient and meaningful planning,

implementation of programmes and their monitoring. Moreover, by the time the plan is made using conven-

tional surveys, the data becomes old and the plan may not be suitable for implementation. It is in this context,

the Orbital Remote Sensing (RS) data and Geographic Information System (GIS) techniques play a major role

by providing reliable, accurate, timely, periodic data and methods of integration of spatial and non-spatial data

to create various planning scenarios for decision making. This type of planning scenarios helps planners and

administrators to view various advantages and disadvantages of different perspectives and select best

perspective for implementation and monitoring. GIS database for various physical and socio-economic

parameters were generated and carried out urban land use suitability analysis, urban sprawl, environmental

sensitivity, and socio-economic analysis using Remote Sensing and GIS techniques. These analyses were

served bases for preparation of urban development plan for the planners and decision makers. Customisation of

user-friendly menu-driven Query Shell in Arc/Info GIS using AML programming language for interactive

analysis, querying and easy access of GIS database. This shell was transferred to planning department for

information retrieval and decision-making processes.

Retrospective and Prospective Planning Efforts

The development plan is normally made on the basis of field surveys using conventional methods. As per this

procedure, the spatial data, particularly on land use pattern, existing transportation network and terrain

characteristics are collected by visiting the areas and personal interviews with Presidents of Gram-panchayat,

Nagar Panchayat/Nagarpalika and the non-spatial data on demographic and infrastructure facilities like water

supply, sewage, communications, electricity etc. are collected from census records or other collateral data.

Later the spatial and non-spatial data is analysed in a related manner and a draft development plan is made.

This plan is then open to planners, representatives of the people, local self-government officers, non-

governmental organizations, leading citizens for suggestions. Suggestions from these people are taken into

consideration in finalising the development plan. Finally land use zoning is proposed based on the local

demands and the estimated population to meet the future planning requirements. Subsequently the town

planning schemes are made on cadastral maps covering an area of about 100 to 150 ha depending upon the re-

quirements.

Objectives and Information Required

The prime objective of the study is to prepare a sustainable urban development plan for the city of Bhopal and

its environs. The preparation of a scientific and environmentally compatible development plan requires

consideration of all components of the environment that exist today and the environment to be created

tomorrow. Thus a comprehensive land use plan should inter relate all elements that form a community. Because

land is a concrete form, any land use plan must be flexible enough to change established uses either to correct

mistakes or to accommodate changing needs. Hence the goals to formulate a sustainable urban land use plan is

to focus on all physical, geographic, historic and cultural characteristics of the city and environs, harmonisation

of sectorial development plans and evolve development portfolio on the basis of carrying capacity of the region,

because the human settlement is nothing but the people, living organism and is not inanimate things like roads,

buildings, gardens and open spaces. Therefore, a city is an integration of folk, work and place. It essentially

means that in preparing a plan one must take into consideration, the number and kind of people living in the

city, their needs for work viz. industries, other employment centers etc. and place includes housing, education,

recreation and all the amenities so as to make the life of the citizens comfortable and happy. In the case of

ailments of a man a surgery for removal of unwanted cancerous growth is carried out. Similarly, the

development of the city should also be carried out on the principles of ‗conservative surgery‘ that is only be

removing or re-arranging of problematic decayed area of the city. Therefore, the problems of cities need to be

diagnosed by undertaking the surveys and preparation of plan by integrating physical, social and economic

aspects of development of the city. Optimal management of a city involves a) proper land management to

promote the right use of land at sustainable level, b) management of environment, c) integrated approach to the

development of water supply, open spaces, utilities, transportation, amenities, infrastructure facilities and d)

sound organization of financial and legislative framework. The preparation of such an integrated plan requires

detailed information on the following parameters.

Terrain characteristics: Physiography, contours, low-lying areas, water bodies, land available for

development, problem areas such as steep and very steep slopes, flood and erosion hazard areas, soil depth, soil

texture, geology, ground water prospects, minerals, construction materials, productive agricultural lands, dense

forest areas, aquaculture sites, temperature, wind, rainfall, sun paths etc.

Land use patterns: Urban spread, area under cultivation and wastelands, area under different types of forests,

good landscape areas, urban land uses such as residential, commercial, industrial, public and semi-public,

recreational and transportation areas, vacant areas for future development, types and intensities of each of the

users etc.

Population characteristics: Number, age, sex distribution, growth trends, migration patterns, estimation about

future, population density, workers and non-workers and occupational pattern etc.

Economic characteristics: Agricultural, horticultural and other land based activities, economic base problems

and prospects, market locations and volumes handled, financial conditions of local authority and agencies

involved and resources for future development.

Transportation characteristics: Types and capacities of available facilities, problems and prospects of

development of the facilities such as movement of goods and people by cars, public transportation, cycle ways,

pedestrian ways, water ways, railways, airways, terminal facilities, transit systems etc.

Housing characteristics: Available stock and its condition, effective demand, need of squatters and effective

dwellers and how to satisfy them, land and financial availability.

Utility services: Water supply and demand, sewerage system, drainage, power supply, telephone services etc.

Community facilities: Educational institutions, recreational areas, medical facilities, markets, clubs, temples

etc.

Methodology

The steps that are followed in the preparation of urban land use suitability map proceed from deciding what

land to develop to when and how to develop it. Therefore, the urban land use suitability analysis encompasses

physical characteristics, constraints and socio-economic possibilities. Basically it refers to the potentiality of the

land for development. Land potentiality not only includes both land suitability as well as land value. The land

suitability designates land according to its physical capability regardless of any planner's conceptual interest.

The land value should index the value of various sections of the land into three categories such as a) market

value which is calculated from past, present and future values, b) subjective value of topographical characteris-

tics and c) values of proximity. The integration of land suitability and land value maps produce a land potential

map, which can be later, combined with socio-economic variables to prepare final alternative development

plan.

Identification of suitable areas for urban development is, therefore, one of the critical issues in the preparation

of a development plan. The land suitability is thus not only based on a set of physical parameters but also very

much on the economic factors. The composite effect of these parameters determines the degree of suitability

and also helps in further categorising the land into different classes of development. Moreover, the process of

suitability assessment is very much dependent upon the prevalent conditions such as pressure on land. If the

pressure on land is too high, it may give rise to a high order of speculation and may lead to development of

land, which is otherwise not suitable from suitability point of view. This clearly states that the level of inputs

would be high due to the market forces. It is in this context, the suitability analysis attempted in this study must

be viewed as a basic "Prioritisation of land for urban development".

Therefore, in the present study, a multi-disciplinary study (field surveys, ground realities, old maps and remote

sensing imagery) has been taken up to carry out land use suitability analysis (Figure-1) identifying the areas to

be used for construction purpose and the areas to be conserved under green belt. The parameters considered for

land use suitability are: (1) Existing land use, (2) Ground water prospects, (3) Soil depth, (4) Soil texture, (5)

Slope in percent (gradient), (6) Flood hazard, (7) Water bodies /Watershed buffer, (8) Soil Erosion, (9) Road

network, (10) Rail nodes, (11) Land values and (12) City Proximity

The assessment of physical parameters gives an identification of the limitations of the land for urban

development. The concept of limitation is derived from the quality of the land. For example, if the

slope is high the limitation it offers is more than for a land, which has gentle slopes or a flat terrain.

Practically, this would mean that the development of the high slope land would require considerable

inputs (finance, manpower, materials, time etc.) and thus may be less suitable as against the flat land

where the inputs required are considerably less. This concept is true for all the land parameters that are

assessed.

All the above mentioned physical parameters have been considered for analysis towards the

identification of suitable areas for urban development in the town as well as its environs. A

multivariate index analysis of these parameters has been carried out by integrating them in GIS

environment. All the parameters were compared to each other and given a weightages based on

significance towards development. All the categories within the parameters were given a ranks based

on their importance towards suitability. Suitability Index was calculated by multiplying ranks and

weightages. Urban land use suitability map generated based on suitability index is shown in Figure-2.

Figure-2 Urban land use suitability map

Result

Urban land use suitability map prepared based on integrated analysis in GIS using various physical

parameters was use full to planners for further allocation of land parcels for different uses and come

out with development planning scenarios. Suitable area required for the future planning will be

allocated in the proximity of the city and inside the planning area limit to prepare the final proposed

land use plan (Figure-3). Thus remote sensing and GIS techniques found very useful for the

preparation of urban development plan.

Integrated Approach for Urban Planning, Development & Management Using Remote

Sensing, GIS & GPS – A Case Study of Hyderabad B.Purushothama Reddy1, K.Santosh Kumar2 & M. Anji Reddy3

Urbanization is an inevitable part of Country‘s economic evolution. The growth of the urban population in

India is unprecedented and it has the world‘s second largest urban population. India has 28 percent urban in

2001 and it is expected that it will be 50 percent by 2030. It means that from 280 million it will increase to 600

million in the next 20 years. This means that there will be tremendous pressure in urban environment which is a

major challenge to the urban planners, administrators and public representatives. The city administration will

have a heavy burden and responsibility in fulfilling the aspirations of the growing city dwellers for various

needs such as housing, drinking water supply, solid waste disposal, roads and other infrastructure network. The

responsibility also lies in augmenting the resources in providing the better living conditions to this growing

population. The capacity of the city management is another major parameter in attending to all these

requirements. In order to face the challenge of providing the needs to the growing population, there is a need to

have an effective and efficient tool. Considering the scale and intensity of the problem, geospatial technology

can play a significant role in this regard. Remote Sensing technology coupled with GIS and GPS have come in

handy in helping to solve many gigantic problems in many fields. But the use of this technology is yet to have

an effective impression in Civic administration. Though practiced elsewhere, the utility is minimal. However

the potentiality of such technology is so enormous that it will be the most important solution for the days to

come in urban planning, development and management. Geospatial Technology should form the core of the IT

strategy of urban administration.

Introduction

Man, while living in human settlements, whether rural or urban, creates a built environment and in the process

disturbs the natural environment system. The environmental problems in rural settlements often arise through

use, overuse and misuse of natural resources which are caused due to lack of alternatives or poverty, while,

environmental problems in urban settlements occur due to transformation of natural environment into manmade

environment. The heavy concentration of population and consequently increasing activities in urban settlements

particularly in larger ones, has strained urban services and severely affected all types of urban environment viz.

physical, social, economic and aesthetic, in these settlements. It is observed that in the world over, this sort of

urbanization has resulted in tremendous pressure on urban infrastructure facilities and services, thereby

affecting the quality of life in our urban settlements to a great extent. In order to achieve healthy living

conditions in our urban areas, it is necessary to resort to innovative and efficient systems of urban planning and

management, which have to play an important role not only in fighting the urban growth, but to accept it as an

inevitable outcome of economic change and to prevent or minimize many negative effects of urban growth,

such as traffic problems, slums and environmental degradation etc. It is needless to say that a comprehensive

information system shall be generated which can control proper urban planning, decision making and also

implementation of various development proposals.

Study Objectives

To study and understand the existing strategies of urban planning, development and management of

Hyderabad city with special reference to urban growth, urban sprawl and population.

To produce high quality digital maps of land use, land cover and base maps for enhancing the capability

of inventory, mapping, monitoring and modelling to many environmental processes and urban planning

using Remote Sensing, GIS, GPS and Field studies.

To develop data base with special reference to revenue generation such as property tax utilities and

infrastructure such as road network, street light, storm water drainage system, water supply, garbage

disposal, greenery, open spaces and horticulture.

To identify the critical success factors in each of the services of the urban local body and to examine

the process of re-engineering through the deployment of Remote Sensing technology, GIS and GPS to

enable more efficient, reliable and timely services in a transparent manner.

To create integrated municipal information system (IMIS) with main parameters such as property tax,

utilities and infrastructure, Garbage disposal and greenery, open spaces and urban forestry and

horticulture using Remote Sensing techniques on GIS platforms.

Data Processing

The project is executed through the following steps

a) Acquisition of satellite data from NRSC, Balanagar, Hyderabad and toposheet from survey of India

(SOI), Hyderabad.

b) Geocoding and Georeferencing of LISS III and PAN digital data by extracting the Ground Control

(GCPs) from SOI toposheet

c) Digital Image enhancement and application of correction models for making the digital data free from

error and distortions in terms of radiometry and geometry of the satellite data.

d) Fusion of PAN and LISS III for merged product preparation of a mosaic corporation. This is FCC mode

and is used for visual interpretation to extract the land use/land cover information by applying both

previsual interpretation ground truthing and post visual interpretation of this image mosaic.

e) Preparation of cartographic output for making the data layer ready for scanning for further GIS analysis.

f) Scanning of cartographic output using Ao scanner, digitized data compatible to ARC/INFO GIS

software.

g) GIS data manipulation and analysis, linking the spatial data file and attribute data file for the creation

of topology.

h) GIS output in the form of land use/land cover map showing various land use/land cover patterns of

MCH jurisdiction.

i) Overlay of major road network on the land use/land cover map for the final project as required by MCH

administration.

Data Collection & Field Surveys

The maps and secondary data from various authorities concerned with the city functions need to be collected. A

set of such maps that can help add layers to the digitized maps is illustrated below:

a) Prevailing Master Plan / General Town Planning Scheme (if any) showing proposed land use zoning,

transport network and sites designated for various public purposes.

b) Maps showing administrative boundaries of ULB jurisdiction, administrative and electoral wards, area

units used by census.

c) Maps showing Cadastral Boundaries

e) Data regarding services like Fire Protection, Cremation and Burial Grounds, Slaughter Houses, Cattle

Ponds, Primary Schools, Primary Health Centers, Parks, Gardens and Swimming Pools etc. In case such

data is missing, the said attribute data is collected through field survey.

f) Locations of facilities provided by State and Central Governments like Railways and highways, post and

telegraph offices, police stations, universities, hospitals etc. also need to be located on the maps and

available data collected through field survey.

g) Existing land use categories like residential including slums, industrial, commercial and healthcare,

educational, sports and sports and recreation facilities.

h) Marking of property boundaries on image through field survey

i) Property tax data identifying properties with their area, use and assessed values

Functions of Urban Local Bodies

Functions are broadly divided into following two categories.

(i) Obligatory functions relate to erection of boundary marks, defining the limits of the city; maintenance of

public streets, roads, public health and other matters relating to sanitation and improvement of the city,

etc.

(ii) Discretionary functions relate to the general welfare of various classes of the population, transport

facilities improvement of socio-economic status of the inhabitants of the city, etc.

The functional domain was expanded in 1994 as per the 12th Schedule of the 74

th Constitution Amendment Act.

In Andhra Pradesh, the Municipalities and Corporation Acts provide for a majority of the functions listed in the

12th Schedule of the constitution. They include:

Urban Planning including Town Planning

Regulation of land use and construction of buildings

Roads and bridges

Water supply for domestic, industrial and commercial purposes

Public health, sanitation, conservancy and solid waste management

Slum improvement and up gradation

Provision of urban amenities and facilities such as parks, gardens, play grounds

Burials and burial ground; cremations, cremation grounds and electric crematoriums

Cattle ponds; prevention of cruelty to animals

Vital statistics including registration of births and death

Public amenities including street lighting, parking lots, bus stops and public conveniences.

Regulation of slaughter houses and tanneries

Conclusion

Integrated urban information is thus needed to provide for such an exchange of data that will not only guarantee

rapid access to data whenever and wherever required but also prevent detrimental duplicalication & degradation

of the system.

Geospatial Technology should form the core of the IT strategy of Urban Local Bodies. The Urban Local

Bodies have valuable and large data in the shape of maps, plans, registers, records etc. The

computerization of the records and GIS are the solutions to preserve, update, retrieve and analyze the

data and helpful for decision-making and advantageous and dependable in crisis management.

Based on the map prepared it helps to designate the properties with unique identification number which

can be used for various purposes including the GIS applications in property tax also. The map also

contains the other features such as roads, streetlights, manholes, dust bins etc. Since the maps are

digitized the regular updating of the map will be easy whenever a building permission is given or a road

is repaired or re-laid.

Due to the usage of the real-time data it saves not only the time and enhances the accuracy but it also

avoids the repetition of the same work and increases the confidence of the public in the administration.

Property information such as type of building, number of floors, number of units, area, density, taxation,

zoning, use of the buildings, tax collection etc are easily known and can be retrieved. Location of all

taxable property with types of uses of the properties can be identified. Since the data pertaining to the

vacant lands are also captured it is very effective in fixing the vacant land tax and collection of the same

as this is one of the major items of pilferage in the absence of clarity.

It also helps to zone the properties depending on the use of the properties. Helps to calculate an amount

of tax to be collected from individual property.It also helps in find out the range of properties based on

the tax-range.Collection of tax can be streamlined by fixing the targets to the bill collectors in issuing

the demand notices based on the routes of the bill collectors. Their work load can also be fixed as per

‗the equal work per field staff.‘Since there is a possibility to attach the photograph of the property to the

land parcel on the base map, it is easy for the Officers to find out the defaulters who have not paid the

tax arrears by making the relevant query.Since there is a provision to attach the photograph of the

property it is to identify the under-assessed properties also.

It is also easy to find out the defaulters with huge arrears of tax and also period of non-payment. It helps

in estimating the revenue generation from property tax arrears of property tax.The tax collection centers

can also be fixed for the convenience of the tax payers based on the spatial distribution depending on the

density of the area.By superimposing the attribute data on the map pertaining to property tax assessment,

demand and collection, it is easy to identify the un-assessed properties, non-issue of demand notices and

defaulters.

Since use of the properties is also shown it is easy to fix up the valuation of the property and also to find

out the deviation or irregularity in the assessment of the property.In view of the spatial location of the

property is known, it is easy to identify the importance of the location vis-a-vis the determination of the

rate of the tax to be fixed.It is easy to bring in the transparency in tax assessment and collection and also

among the staff and also the citizens.

Recommendations

A comprehensive and integrated Municipal Information System integrated with GIS has become

important and crucial for efficient, economic, meaningful and people-friendly Municipal

Administration. The system should be based on the principle that a data set should be stored and

maintained within the department where expertise for that type of data is available but be freely and

easily available for all the other departments that require this type of data. The system should not be an

isolated or separate unit but integrated and implemented into all the departments and operated by the

people those need and use the information.

Property identification code / House Numbering System shall be introduced to introduce a unique code

which would identify the property and this should be used by all the departments and other Government

Departments, so that it would be useful to identify each property in the city.Self-assessment (SA) shall

be made statutory and submission of wrong particulars for assessing the property tax shall attract

penalty.The SA application shall be in simple format and ordinary citizen shall easily understand the

method of calculation.

Spatial data through GIS application shall be utilized for accurate and correct assessment. The

Collection of property tax shall be through e-seva, banks and on-line only and field collections (personal

contact) shall be banned. The staff shall be given training to use the GIS application for verification of

the collection, reassessment, usage of the building etc. All the previous property tax records shall be

computerized and the GIS database shall be regularly updated. Special teams shall be constituted to

survey and assess the properties. The correct plans shall be prepared on CAD or similar application so as

to know the plinth area, floor area and usage of the building so that the assessment can be done

automatically.

All the building applications shall be submitted along with CAD drawing and after the approval is

accorded the GIS database shall be updated instantly, so that the same can be used for assessment of tax

and also to check unauthorized deviations to the approved plans. The entire GIS database shall be placed

on the web facilitating the citizens to browse the data pertaining to the plinth area, floor area, property

tax – paid, balance etc. The availability of data and maps are needed in the formation and maintenance

of roads. In number of instances the data collection, storing and retrieval of the data of roads are time

taking, cumbersome and incomplete. GIS application solves all these problems. The data including maps

shall be regularly updated.

GIS database for manholes, street lighting, potholes, works done, scheduling, etc has to be built and

used. GIS application is of a major help in storing and retrieving the data of details, which are

underground such as pipelines, drains with their dimensions. In the formation of new roads and to study

their impact can also be done through GIS application. The present grievance redressal mechanism shall

be linked to the road inventory and shall be used after analyzing the same on the GIS application. The

data shall be accessible to all the staff members so that the redressal mechanism will be instant and

monitoring will be simple. The GIS maps help to identify the areas based on the quantity of garbage

generated and problem areas can be identified and monitoring can be done effectively.

Garbage disposal can be streamlined with the GIS database. Optimal routing of the vehicles is possible

through GIS.No. of trips of each garbage lifting vehicle can be easily monitored through GIS maps and

by instant forwarding of the data through handsets with the staff. Web based GIS application in urban

administration shall be made mandatory for effective governance and shall be a pre-requisite

qualification for making the Urban Local Body (ULB) eligible for any financial assistance from the

government.

Introduction

The dimensions of the urban scenario in India are mind boggling. The number of people living in cities in 2030

will be 590 million which is twice the population of the United States today. There are 42 cities with population

above 10 lac now and this will go up to 68. The number for Europe today is 35. To meet the needs of this

projected growth India needs a capital investment of Rs 60 trillion, 700 to 900 million sq m of commercial and

residential space, 2.5 billion sq m of paved roads and 7400 million km of metro rail and subways. These

numbers indicate the humongous nature of the task on hand. It is something that no country in the world has

faced or will face.

This task requires a fivefold approach addressing funding, governance, planning, sectoral policies and pattern

of population distribution. The JNNURM is the first effort by the government to address these issues. The

JNNRUM has identified geospatial technologies, specifically GIS as a tool which is needed to achieve some of

the goals of governance and planning. One goal is the reform of property tax with GIS, so that it becomes major

source of revenue for Urban Local Bodies (ULBs) and arrangements for its effective implementation so that

collection efficiency reaches at least 85% within next seven years. The other is the introduction of system of e-

governance using IT applications like, GIS and MIS for various services provided by ULBs/Parastatals. Even at

this rather elementary level of induction of geospatial technologies it is depressing to note that though twenty

six towns have implemented the eight mandatory IT functions but not a single city has operationalised the GIS

part.

Problem Definition

The problem is that of an urban planning mindset which is tied to ‗building permissions‘ and ‗tax collection‘.

Very few metropolitan cities have planning departments and those that have are staffed at best by eight to ten

planners under an engineer who are busy with building permissions rather than planning because they are

understaffed, under budgeted and lack modern geospatial tools like GIS. The need is for 80 to 100 planners for

a large city and their domains of expertise should cover the various sectors of planning as well as economics

and architecture. Needless to say they also need to be able to handle modern geospatial technology in their

planning process. This technology goes much beyond a simple GIS and encompasses new data acquisition

systems, ERP and modelling. Thus, while JNNURM provides the entry of geospatial technologies into urban

management through its stress on use of GIS for efficient tax collection and rational building permissions,

geospatial professionals should use this opportunity as the thin edge of the wedge to push these technologies

into city and town planning which recognizes and accounts for social, cultural and economic factors along with

engineering considerations.

According to Wikipedia ―Urban planning is a technical and political process concerned with the control of the

use of land and design of the urban environment, including transportation networks, to guide and ensure the

orderly development of settlements and communities. It concerns itself with research and analysis, strategic

thinking, urban design, public consultation, policy recommendations, implementation and management.‖ Figure

1 shows the concept of GIS and urban design developed by Batty and others. It illustrates the multi-dimensional

nature of the activity.

Figure 1 Concept of GIS and Urban Design (Batty et.al.)

AM/FM

One of the earliest and most successful implementation of geospatial technologies for urban management goes

by the name of Automated Mapping and Facilities Management or AM/FM. AM/FM traditionally has

addressed utilities like power, water, sewerage and transportation which are based on a network model of the

data. With the additional capabilities of spatial analysis enabled by the geographic data model of a GIS, these

applications have been enhanced and newer areas have opened up. Some of the tasks that are enabled include

job design, engineering and estimation and integration with work flow management, customer information

systems and outage management systems. The systems can be web enabled to provide access across the

enterprise. Field information can be integrated and activities like field maintenance can be automated. A GIS

provides spatial visualisation, spatial query and modelling capabilities which make these applications more

effective.

However, where GIS comes into prominence is in new areas of AM/FM. An example is the computerisation of

land records. Traditionally these records are held as paper or cloth maps with the ownership information in a

ledger. The bane of these records is updating and here the use of GIS to digitise the maps and georeference

them using GPS control points is an excellent application of automated mapping. The ledger data is transferred

to a linked database to provide the attribute data. These maps can be distributed over the web at a nominal cost

to the owner. Another area that has enormous potential is facilitating planning, design and construction of

facilities and infrastructure projects. For proper planning, optimum utilization and management of the utilities

there is a need for detailed information about the extent and spatial distribution of various urban and rural

Page 19: INDIAN SOCIETY OF GEOMATICS secretary@isgindia.org …isgindia.org/pdf/ISG-NL-JAN-2012.pdf ·  · 2017-01-2420 to 24 5. Development of 3D City Models ... Shweta Jaiswal & late Dr

utilities and the existing condition of infrastructure and utilities. Planners need spatial information on multiple

themes, their variation with time and tools for multi criteria analysis.

In the Asian context geo-informatics based utilities management is in a formative stage. The databases are

being created and conceptualized for the applications addressing faster decision making as well as actual

planning of the utilities. Certain issues need to be addressed during the spatial data base creation phase of the

utilities management.

Creation of the datasets

A major headache in AM/FM systems is availability of data. Old Asian cities and towns rarely have well

preserved maps or diagrams of water and sewage pipeline routings. Creating such data using radar and other

tools is expensive and time consuming but without this basic data the systems will have limited use. Even

where data exists there is a plethora of formats, media and standards which have to be reconciled. The worst

problem arises when the same theme is covered in different maps in different departments. Harmonising the

contents into one map is often a Herculean task. Yet another problem is the currency of the data. Update cycles

are irregular and the available data may not reflect the ground realities.

High Resolution Imagery

There is a possibility of using high resolution imagery for data acquisition. Today, metre and sub metre

resolution imagery is available from low earth orbiting satellites which are highly agile and use techniques like

‗step and stare‘ to image designated targets. In the process they compromise on the time of imaging and the

total coverage area. However, the volume of data increases as the square of the resolution. Data storage and

preservation problems will become significant as data assets increase. Furthermore such high resolution

imagery interpretation requires the application of techniques of image understanding rather than statistical

pattern recognition. A human interpreter who can, by looking at an image, differentiate between a canal and a

river is actually using shape and context information. Image understanding software may be based on neural

networks and on artificial intelligence techniques which can also take into account such features. The ‗step and

stare‘ technique of imaging results in imagery with oblique viewing angles. In urban environments tall

structures appear with their apexes displaced away from the viewing direction and features on the side opposite

the viewing side are occluded. Any mapping in such situations will require stereo pairs to be able to generate

urban Digital Elevation Models and fill in the occluded areas. These will double the cost but the urban DEM is

a product very much in demand by the communications industry among others and will offset the increased cost

of mapping. High resolution imagery has brought in a number of new applications in the area of Location

Based Services. Such imagery used as a map on a GPS enabled 3G mobile phone can become a significant LBS

application.

Two other imaging technologies are also capable of high resolution imaging. Synthetic Aperture Radar is able

to give metre level spatial resolution but the imagery interpretation requires special expertise. The other is

Hyper-spectral imaging which provides very high spectral resolution. Both these technologies have been

overshadowed by the explosion of sub metre optical imaging.

Standardisation / Codification of the information

To harmonise the datasets coming from various sources, a set of standards are needed that can address issues of

required accuracy, techniques to be used, content of database, and the format guidance to users. This would

make the datasets more interoperable, easy to understand, well organized and easily retrievable. This is shown

in Figure 2.

Updating of the datasets

A mechanism for updating of the datasets should be evolved. Certain datasets require updating on regular basis.

This can be done by making easy updating of the datasets at the users end. For example in case of health

utilities, the performance of certain utilities like the performance of a Primary Health Centre, Sub centre are

being monitored monthly, data is collected every month. Such datasets require updating every month.

This can be done by

Capacity building of the respective departments,

Evolving simple updating mechanism wherein the updated datasets are regularly incorporated.

Certain geomatics based applications like web based GIS where in the new files can be imported and

updated automatically in the system

Using crowd sourcing by enabling citizens to update information through the web and incorporating

that information after due validation

Cost Effectiveness

Another issue for mapping of the urban utilities would be the cost involved. For ease of use, easy deployment

and compatibility to the available hardware and software, there is a need to develop low cost geo-spatial based

DSS for faster adaptability of the spatial application to the grass root level. Another aspect is to make the

system scalable so that it effortlessly grows in terms of data, scope of applications and number of users.

Scalability can be ensured by adopting open standards for the data models and the software and also

partitioning the system into logical units avoiding duplication.

Mobility

With the advent of broadband mobile systems AM/FM could also become mobile and the data could be

accessed from remote locations on a PDA through wireless networks. This would be a huge boon for outage

management and other field jobs.

3D Cities

Cities have a third dimension, height. As land becomes scarce cities grow vertically and this adds to the urban

management problem. Systems like AM/FM even when enhanced with GIS capabilities fail to include this

Figure 2 Organisation, Harmonisation and Standardisation

dimension in its models except in an indirect way through enhanced demand for services. CAD provides an

ability to add this third dimension but does not have the capabilities of analysis. Technologists have found a

way to integrate both GIS and CAD into one platform with a technology called Geodesign. 3D CAD drawings

of buildings are georeferenced and placed on a map or imagery to give a very realistic visualization.

Figure 3 3D CAD Model of DAIICT Campus (LOD3) on Google Image

The 3D models can be at various levels of detail, LOD. The lowest is LOD0 which is more familiar to GIS

practitioners as 2.5D view. Here the terrain is accounted for and the building sites appear in their true terrain

position. In LOD1 the footprints of the buildings are extruded to scale height. In LOD 2 the building textures

and roof details are added. LOD3 includes architectural details and LOD4 includes internal building details.

The OGC standards relevant to Geodesign are CityGML.

3D city models are extremely useful for many applications like telecommunications tower siting, visualising

hidden assets like underground pipelines, training of municipal staff to handle disasters, simulating disasters,

harmonising new developments with existing architectures, transportation planning and many more.

LIDAR Imaging

Another way to obtain 3D model data is to use LIDAR imaging. The LIDAR creates a points cloud of the

returns from objects and these can recreate the object as each point has a three dimensional reference. LIDAR

can be used from aircraft and on ground based vehicles to create the images.

As a LIDAR image is of photogrammetric quality it can be used to quickly scan an area for building law

compliance thus removing the need for inspectors to visit sites and physically measure objects. An inherent

advantage of combining LiDAR with digital video imagery is that it allows the customers to load both LiDAR

and imagery into a GIS system and do inventories, maintain and manage assets from their office. The real

advantage of these technologies is that multipurpose data is being collected simultaneously which has different

horizontal applications. Encroachments and illegal constructions can be trapped much faster using this

technology.

Building Information Model

Monitoring and planning for building activity is a multidimensional task involving

several sectors. Building information model or BIM is a very versatile tool which

integrates geographic and CAD data into a unified system. Building information

modelling includes geometry, spatial relationships, light analysis, geographic

information, quantities and properties of building components. BIM provides a single

integrated model to engineers, architects, contractors, and clients to work with. This

enables them to have reliable, coordinated information at every stage of a project

lifecycle—from planning to design through construction and ultimately into operations

and maintenance.

Conclusion

The issue of urban planning is complex and requires a structured approach. It has been suggested that there

should be a cascading planning approach starting with a 40 year regional perspective plan and coming down to

annual city plans. Such activities will be very data hungry. Geospatial technologies along with other modern

data handling systems like ERP will be essential for such planning activities. While the JNNRUM is a good

start India will need many more JNNRUMS to be able to come to grips with its urban woes. Upgrading of

planning tools to include modern digital systems is urgently needed. Capacity building to geospatially enable

the existing workforce and create a new workforce of geospatial savvy professionals is also a major need.

Introducing the Hierarchical Development Of Survey Methods

Information on ownership of land is perhaps the most important prerequisite for any developmental activity.

The concept of measurement of land and recording the ownership rights for land holdings dates back to the

ancient times. In Maharashtra, this further got refined during the Mughal times and the period of great emperor

Shivaji. These were primarily used to rationalize the levy and collection of land revenue from the landholders.

The land records available today are continuation of refinements over the initial city survey carried out by the

City survey department of the British period. The data is available as a mix of maps and records in the field

measurement books (FMB) consisting of variable scales (1: 500 scale, 1:10,000) and different measurement

system like feet or meter units. The archival medium is also varied consisting of cloth, paper, blueprint, Xerox,

tracings, etc. Numerous survey methods were used in the 19th and 20th Century. Many of these systems led to

inaccuracies and were modified time and again. However, the Bombay Survey System and Madras Survey

System records, which evolved after 1880 were highly accurate and were adopted directly or with slight

variations as a standard in many States.

Present Need for Digital Geo-Correlated Cadastre

Updating of city cadastral maps using conventional mapping techniques of land survey is immensely time

consuming, cost ineffective, and human-resource hungry and therefore not feasible in near future. The city

cadastral maps in most of the states have not been updated for majority of the corporations and councils since

last 3 to 4 decades. The new cadastres have not been prepared for the upcoming townships and for the

extension of the existing old cities. Different map scales, lack of standard map symbology, lack of feature

continuity in adjacent maps, non-standard legend, missing coordinates or control grid, different type of

annotations for depiction of local landmarks are the vital issues which surfaces as primary concerns, when the

entire record of city survey is collated on the global level.

Since the existing maps of city survey are based on the local coordinate values, their geo-correlation with the

earth centered projection system is not available directly. The geo-correlation of each and every mappable unit

of city survey number with the satellite imageries is the need of hour. The digital geo-correlated cadastral

database is in consensus with the national and international efforts towards standardized GIS datasets. The

National Spatial Framework (NSF), Open GIS Consortium (OGC), National Spatial Data Infrastructure (NSDI)

and Global Spatial Data Infrastructure (GSDI) are some of the examples. Geoinformatics has now become an

effective tool in decision support information systems. The concept of land records management in a GIS

environment is a computerized storage, retrieval and analysis technique, which is a universally accepted

methodology for numerous information management applications.

Methodology

A new methodology for conversion of city survey records into digital format and the geo-correlation of city

survey with satellite data has been devised and executed by MRSAC for the entire state of Maharashtra and the

highlights of the maiden Spatial Information Technology approach is discussed below.

Scanning

Action - The maps in vogue (Prachalit Nakashe), procured from the land records department are procured and

scanned.

Advantage – The record of the city survey is browsed, gaps found, inventory updated and data archived in

digital media

Reference Grid

Action - A reference grid is constructed in a cad environment using the local coordinate values provided on

the sheets. Meters are used as standard units for generation of the grid. The coordinates were converted to

meters, in cases where the values are in feet. The grid so obtained pertains to ground coordinates in the

scale of 1:1 and has origin (0,0) for each corporation / council.

Advantage – This grid forms a control for assessing the area in the local coordinate system used during the

time of original survey.

Process Of Rubbersheeting

Action - The scanned maps are fitted on the reference grid corner coordinates in the cad environment through

rubber sheeting on 1:1 ground coordinates. This helps in mosaiking and checking of the scanned maps for

adjacency and continuity of features.

Advantage – The task is executed to remove the errors and deformations induced in the process of storage

and scanning.

Digitisation / Vectorisation

Action - Scaling down the maps from 1:1 ground coordinates to 1:500 meter scales

Advantage – It is a prerequisite to bring all the maps on a common scale. The vectorisation is carried out in

the cad environment on 1:500 scale using the heads up digitisation.

Geo-Correlation

Action - Geo-correlation of city survey maps with satellite imageries, already referenced to the earth-centered

coordinate system, is achieved in a cad environment by simple process of ‗scaling‘ and ‗rotation‘ of the entire

mosaic containing raster, vector and reference grid.

Advantage – This process of geo-mosaic generation has distinct advantages over image-to-image registration

and transformation / rectification process using ‗TIC‘ & ‗Ground Control Points (GCP)‘. It is observed that

this process of geo-correlation preserves aspect ratios of original map sheets, unlike in other processes using

transformation algorithms, where distortions are introduced for areas with non-availability of proper GCPs.

The database would also provide a strong support for the Disaster Management Planning in the difficult

urban setup.

Out of the innumerable possibilities a few major areas already being harnessed are as :

Regional plans for the district – Village / Zone level Existing and Proposed LandUse plan on Cadastral

basis.

Development plans for the Councils and Corporations - Parcel level Existing and Proposed LandUse

plan

Ready Recknors for the land valuation – Vicinity of land parcels to the developmental indicators based

on infrastructure facilities.

Property Mapping, Valuation and tax assessment – Building Foot Prints, building types (Pakka /

Kuccha), Floor Area Index,

Decision support for civic authorities (Civic Information system) - Linkage of Building Permit to the

Spatial records, Map Linkage to the Municipal Records, Restoration of the not functioning Municipal

Records System, Assistance to the tax billing and Collection

Application projects have already been implemented with the use of geocorrelated cadastre for the

Maharashtra state

1. Civic information system,

2. Mangrove mapping on 1:500 scale

3. Slum mapping and monitoring,

4. Utility inventory in the corporation

5. Non-Agriculture permission in Urban influence areas

6. Police Information system

Conclusions

The present approach is a success story of Spatial-IT engineering solution for addressing the

requirements of Land Records Management System.

Standards defined at various levels for 1:500 scale.

It attempts to preserve, maintain and analyze records in computer format accruing the numerous

benefits associated with this technology.

Use of Satellite images, Cadastral Maps, administrative Boundaries, Location Based Services

comprising Networks and Location Analysis is the requirement, on a day-to-day basis, of decision-

makers in almost all application areas.

MRSAC has used this methodology and work of more than 220 Corporations and councils have been

completed on these lines and generated the huge database for the urban applications.

Introduction

Urban models are computer-based simulations used for testing theories about spatial location and interaction

between land uses and related activities. They also provide digital environments for testing the consequences of

physical planning policies on the future form of cities. As computers, software and data have become richer,

and as our conception of the way complex systems such as cities grow from the bottom up have been

reinforced, urban models have moved from theories and structures that articulate land use and movement in

aggregate static terms, to more dynamic models of individual behavior from which spatial structure emerges.

Urban India today, faces serious challenges of growth and its management. Across geographies, the issues of

urbanization manifest in the form of overcrowding, congestion, insufficient infrastructure, inadequate service

provisioning mainly in terms of drinking water, sanitation, energy, transport, solid waste management,

environmental degradation, and pollution, etc. These, along with the poor management of rapid growth, affect

the socio-economic development of the country. 3D city models of urban areas are an important input for many

applications in the field of urban monitoring. Besides the creation and updating of maps from sprawling urban

settlements the models are also used for simulation and planning in case of catastrophic events like flooding,

tsunamis or earthquakes.

The present study aimed at development of techniques for 3D modeling of buildings for urban morphological

analysis and to implement encoding standards prescribed in ‗OGC City GML‘ for urban features. An attempt

has been made to develop 3D city model with level of details 1 (LOD 1) for part of Ahmedabad, Gujarat. The

broad methodology involved use of a high resolution merged product classifying and extracting the urban

building foot prints using object oriented classification, generation of digital surface models using satellite

photogrammetric methods, extracting the average DTM and Urban 3D features extraction.

Objectives and data used

The main objective was to develop a methodology for building foot prints from high resolution merged product

and to develop procedures for 3D modelling of buildings. A part of Ahmedabad city was selected as study

area.Cartosat-1 Stereo (13 FEB 2010), and IKONOS merged data were used in the study.

Methodology

A method for automatic derivation of coarse models of

urban structure is therefore of great use. The strategy of

the approach is listed below.

DSM and Ortho Image Generation

Digital Surface Model (DSM) was derived from High

resolution stereo satellite data (Cartosat-I) using Rational

Function Model. Rational Polynomial Coefficients

(RPC's) are supplied along with Ortho kit products for

high resolution stereo images. A standard methodology

was adopted for the generation of DSM and Ortho Image.

It comprises of reconnaissance survey and DGPS survey, identification of GCPs from reference data, stereo

data analysis using RPCs and updation of RPCs using GCPs, generation of DSM, Orthoimage, accuracy

assessment of DSM and orthoimage. Triangulation accuracy was better than 3 m and 5m, respectively in

planimetry and elevation, respectively.

Extraction of Building Footprints

The footprint of buildings as well as the land use was extracted using object oriented classification of high

resolution data merged product (IKONOS data). Building footprints were extracted using eCognition software.

The major steps involved are (1) Creating a hierarchical network of image objects using the multi-resolution

segmentation. The upper level image segments represent small-scale objects while the lower-level segments

represent large-scale objects. (2) Classifying the derived objects by their physical properties. This also means

that the class names and the class hierarchy are representative with respect to two aspects: the mapped real-

world and the image objects' physically measurable attributes. Using inheritance mechanisms accelerates the

classification task while making it more transparent at the same time. (3) Describing the (semantic)

relationships of the network‘s objects in terms of neighborhood relationships or being a sub- or super-object.

This usually leads to an improvement of the physical classification res. the class hierarchy and (4) Aggregating

the classified objects to semantic groups which can be used further for a so called ‗classification-based‘

segmentation. The derived contiguous segments then can be exported and used in GIS. IKONOS multispectral

image was used as base image for 2D feature extraction (here building footprints).

Extraction of Building Heights from DSM

Average elevation values at open areas were subtracted from DSM to find the actual elevation of the urban

features. From this normalised DSM (nDSM) average elevation within the building footprints were extracted

for computing the building heights.

Generation of 3D City Model

Buildings are the most important part of a 3D city model for many applications. Manual modeling can lead to

very good results but is only feasible for very small areas. Visual analysis is an important component of

landscape planning and parts of a process which would identify the most suitable site for a development of a

project. In traditional 2D maps scale has been the factor defining the features on the map and for 3D

environments the concept of level of detail somehow replaces the concept of scale. Features represented in

LOD0 use representations that correspond to earth surface features. LOD1 describes a simple extruded

representation, LOD2 a textured representation where individual polygons are classified, LOD3 a detailed

geometric representation and LOD4 indoor environments. In the present study, an attempt has been made to

provide a procedure to LOD1 model. The extracted building footprints with building height derived from the

(nDSM), along with the merged product were overlaid over DEM. Level of Detail 1 (LOD 1) 3D City Model is

shown in Figure. 4.

Results and Discussion

Figure 1 shows the stereo data (Fore and Aft) of Cartosat-1. The stereo analysis carried out on Cartosat-1 data

provided triangulation accuracy better than 5 m in elevation and 3 m in planimetry. The DEM and orthoimage

are shown in Figure 2. Figure 3 represents the semi automatically extracted building foot prints. Figure 4

shows the 3D city model with LOD 1.

Conclusion

The study was carried out to demonstrate a procedure for generating 3D city model at LOD 1. The accuracy of

DSM restrict the delineating the building heights. This also prevents one to go for the details as listed in LOD

2.

Introduction

This paper demonstrates various initiatives undertaken by Space Applications Centre (SAC) at Ahmedabad in

introducing spatial information for decision making pertaining to administration and campus infrastructure

management. A 3-D spatial information system was developed for SAC campus integrating remote sensing and

GIS technology with the CAD drawings of surface and sub-surface infrastructure. Geo-informatics was used for

optimizing water distribution network layout within SAC campus so as to cause least interference with existing

underground utility lines. Least cost distance method was used for alignment of water distribution network

within the campus leading to cost and energy benefits. In addition to facilitating within-campus infrastructure

management, GIS were applied towards welfare of employees. A web-based spatial information system for

medical facilities was developed to search nearest doctors, and to provide shortest route from employee‘s

residence to hospitals, medical officers, and specialist doctors. The spatial database of employee residences and

medical facilities was utilized for optimum distribution of medical facilities within Ahmedabad city. GIS

technology was also utilized for optimizing route of buses operated by department within Ahmedabad city.

The paper is divided in to five sections. First section discusses about 3D spatial information system for SAC

campus. This is followed by application of least cost distance analysis for alignment of water distribution

network pipelines within SAC campus. Third section discusses about medical facilities information system in

Ahmedabad city for SAC employees. Fourth section briefly highlights optimisation of route for buses operated

by the department for employee transport. Each of these sections highlights the benefits achieved by the

organisation in harnessing geospatial technology for decision making. The paper concludes with argument for

encouraging applications of remote sensing and GIS technology in benefiting organisations.

3D Spatial Information System (3D-SIS)

The paradigm shift from 2D information system to 3D information system in the recent years has evolved the

necessity for generation of 3D information system for the planning and management purposes. Most of 3D-GIS

applications tend to focus on visualization such as walk-through animations or scenic simulations. However,

true strength of 3D spatial information lies in 3D analysis capabilities, which can immensely benefit the modern

city management, particularly for the tasks of spatial planning, communication, emergency management etc.

These tasks can be realized easily and effectively by the 3D representations of the spatial and thematic attribute

information together within a geographic database.

The main campus of SAC at Ahmedabad, which is spread over 34 ha land area, accommodates several

buildings used as laboratories, facilities, conference rooms, administrative complexes, and seating places of

over 1800 employees. A 3D information system for the campus was contemplated with primary objective of

management and security of campus infrastructure. In order to create a powerful information system, the non-

spatial data about employees was collected from Manpower & Information System Division (MISD), and

building plans of all buildings in the campus were collected from Construction and Maintenance Division

(CMD). This data was later organized in the geo-database. Cartosat-2A panchromatic data and LISS-IV data

covering SAC campus was procured, processed and geo-referenced. CAD drawings of building layouts and

other utility layers were registered with the satellite image. These individual layers were subsequently

integrated in GIS and attribute information was attached. 3D building blocks and floor wise layout details were

hyperlinked to each floor of the respective building block. Detailed attribute information with respect to the

floor and rooms were attached based on building and room numbers. Additional information such as road, lamp

post, trees, lawns, etc. was overlaid to visualize entire campus in 3D.

Layout of Water Distribution Network

Water distribution usually accounts for 40 to 70% of the capital cost of the water supply projects and hence its

proper planning is very much essential (CPHEEO, 1997). An optimum layout for distribution network

minimizes the cost of construction and operation. A distribution network should avoid cutting across steep

slopes, avoid excavation of existing built-up areas, avoid conflicts with existing utility lines, and minimize the

head loss. Geo-informatics can assist in locating lowest cost network layout by simultaneously taking into

account multiple parameters affecting the cost.

GIS was used to optimize the layout of pipelines for distribution of the Narmada water supplied by Ahmedabad

Municipal Corporation (AMC) to various buildings within the campus. As the campus is covered by different

types of paved and unpaved surfaces, it is desirable that interference of proposed layout with paved surfaces is

minimized. Furthermore the dense network of utility lines that occupy the sub-surface terrain of the campus

also requires to be avoided. The distribution network layout was proposed using least cost distance analysis

which substantially reduced the conflicts with the paved surfaces within campus, and sub-surface utility lines.

Public domain software EPANET, developed by Environment Protection Agency (EPA) of United States of

America (USA), was used for hydraulic analysis of the pipe network. The water distribution network thus

prepared was successful in reducing energy consumption by 13.0 m, and reduced intersection with paved

surfaces by 54% in comparison to the design proposed without using GIS.

Medical Facilities Spatial Information System

The healthcare facilities of all employees (including the retired employees) of SAC and their dependants

amounting to about 7000 beneficiaries are covered under Contributory Health Service Scheme (CHSS). CHSS

maintains its own dispensaries, and has empanelled Authorized Medical Officers (AMO), specialist doctors,

and Hospitals, spread all over Ahmedabad catering to the medical needs of employees. The location-allocation

of health services with respect to employees has been a major challenge for the Medical Advisory Committee

of SAC as it has direct bearing on economics of medical service delivery, and the quality of medical services

provided to the employees. With growing size of organization and outwardly expansion of the city, the

governing body of CHSS realized the necessity of introducing GIS for managing medical facilities. Towards

this, an exercise was carried out for optimization of medical services with respect to the location co-ordinates of

both employees and doctors.

Geo-tagging of all employee residence locations and medical facilities in Ahmedabad was undertaken on very

high resolution ―Cartosat-1 PAN and IRS-P6 LISS-IV‖ merged product data, using the web application.

A web-based spatial medical facilities information system was developed using Oracle Spatial 11g as database

for storage and retrieval of spatial data, and Oracle Application Server‘s MapViewer for visualization of spatial

data over intranet. The website provides not only the shortest route from employee residence to any medical

facility, but also searches for nearest AMO and specialist doctor/ hospital from employee‘s residence. The

spatial database was also employed to determine equitable distribution of medical facilities across the city and

suggesting assignment of employees to the respective nearest authorized medical officer. The study

demonstrates role of information in spatial domain and decision-making by the Medical Advisory Board

towards good governance.

The spatial database of locations of employees and medical facilities provided various inputs to the Medical

Advisory Committee of SAC for improving its decision making. The data was used in defining zones and

analyzing zonal distribution of medical facilities, assessing workload on medical officers, and analyzing spatial

distribution of employees with respect to medical facilities. Moreover, it provided spatial search of medical

facilities and their shortest route from employee residences as service to SAC employees.

Optimisation Of Bus Routes Using Network Analysis

Network is a system of connected linear features that form a framework through which resources flow. The

network data set is very important in various planning activities to determine the optimal paths and to site a

service centre between the source and the linear features. The features may be streets, power lines, communi-

cation lines etc. Proper planning of these routes in optimal paths is very much essential for smooth

transportation and to save time, distance, fuel, and money. It is in this context an attempt has been made using

ARC/INFO GIS NETWORK to generate optimal paths for SAC transport service.

In 1994, SAC was operating 17 buses in different routes to pick up/ dropping of its employees from residence

to office and back. Nearly 850 employees were availing SAC transport service. As the expenditure is

continuously moving upwards on account of spiralling fuel prices, the need towards optimisation of bus routes

with respect to time, distance, and fuel consumption was realized. Thus a methodology was developed using

both RS and GIS Network techniques for optimising SAC transport service. Optimum paths have been

determined taking into account the traffic volumes on different types of roads, turn impedances at the

intersection of roads, traffic rules and regulations prevailing in the city. The study demonstrated that a

considerable amount of travel distance, time and cost on oil consumption can be saved by optimizing the bus

routes. An amount of about Rs.71, 280/- per year was saved on fuel cost alone apart from the maintenance,

wear and tear charges. This saving is in addition to the saving of a bus i.e. SAC has to operate only sixteen

buses instead of seventeen buses. It is also possible to find out alternate paths in case of curfew, alteration of

different routes etc. Moreover, the analysis can also assist in determining the optimum paths to access any

facility viz. Medical, Educational, Recreational etc. Therefore this methodology can be applied to any service

which is dependent upon linear features viz. telephones, drainage etc.

Conclusion

The spatial decision-making is gradually but steadily penetrating all spheres of life. Institutional campuses

spreading far and wide offer tremendous potential in terms of applications of geo-informatics. This study

demonstrates several avenues of applications of remote sensing and GIS technology that may be applied in

management of campus operations and welfare of employees. The study paves the way for more direct

involvement of these modern technologies in the processes of administration at institutional levels. Space

Applications Centre (SAC) at Ahmedabad has pioneered the use of remote sensing and GIS technologies for

the natural resource management of the nation and its environ. This study is extension of these very

technologies in more direct and intangible manner towards.

Introduction

Urbanization is an index of conversion from rural economies to urban, the process through which the ratio of urban

and rural population gets changed in favor of urban settlements. The urban population of the countries of the world

is growing at a phenomenal pace. India is no exception to the prevailing trend. Number of population residing in

urban area has increased from 2.58 Crores in 1901 to 28.53 Crores in 1990-2000. The cities attained tremendously

large population size leading to virtual collapse in basic urban services. The rapid growth of urban population and

the escalating demand for basic services has an obvious implication in terms of infrastructure and service needs of

the cities resulting into serious deterioration of service quality. India's inadequate infrastructure has long been

identified as a serious basis for holding back the economy's growth. In 1994, it was Government initiatives to make

Indian industries globally competitive. Considering the vital role of infrastructure, the government decided to

constitute the experts‘ group to consider issues related to the commercialization of infrastructure. The high-powered

Rakesh Mohan Committee -1996 (constituted by Government of India under the leadership of Rakesh Mohan in

1996) had done an exhaustive study of infrastructure and made recommendations of a far-reaching nature carried

out as India Infrastructure Report (1996).

Inadequate infrastructure in Indian cities

This article particularly focuses on the appraisal of India Infrastructure Report-1996 and presently implemented

policies of Jawaharlal Nehru National Urban Renewal Mission (JNNURM). The attempts have been made to

examine the recommendations given in the Rakesh Mohan Committee, India Infrastructure Report. Further it tries

to study the present policies and various strategies for implementation and financing, recommendations and reforms

considered by the Government of India to implement the process of provision of effective infrastructure

development for the identified Indian cities given in JNNURM, whether it is converge or diverge than the approach

suggested in the India infrastructure Report (1996) and what further progress has been made.

This particular India Infrastructure Report has identified the dimensions of the problems and the resources needed

for provision of infrastructure. The Report examines all issues and provides directions for policies reforms which

can help in greater commercialization along with the promotion of public-private partnership, estimates of the

investment required over the next 10 years, from 1996-97 to 2005-06. The Report has contributed to improving the

understanding of the many issues involved in the commercialization of infrastructure and set the stage for

assessment of infrastructure financing requirements.

The Report also discusses about the existing capital market frame work in the country and makes projections for the

sources of funds would be required for the investment. Recommendations were made on the role of government in

developing the capital market for intermediating long term saving to long infrastructure investment. Further it

provides policy directions required to activate the long term debt market, essential for infrastructure investments

and overall regulatory framework governing different infrastructure sector. It has estimated the total requirement

for urban infrastructure development during the decadal period to be enormous Rs. 2,500,000 million. Whereas the

funds from the governmental sources for urban infrastructure development, fall short by more than 10 times to meet

the actual requirements of funds. The implementation of the policy direction proposed would have been feasible to

commercialize many segments of infrastructure sector and made it possible to raise the required volume of

resources. According to this Report, if new policies made for infrastructure investment had been accelerated in this

manner, the target would have been achieved over ten years ago, but may be due to the changes in the political

setup of government, the course of action and directions for the implementation could not accelerate and somehow

it did not become visible to the fullest extent. In 1998, however, within two years of the submission of the Report,

there has been limited progress on its recommendations, leading to inflation, accelerating the urgency of the need to

address the widening gaps between the demand and supply of infrastructure.

Over the years, there has been a wide gap between the requirements and allocation of funds. Urban sector was

mainly focusing on growth-oriented projects rather than welfare of community development. The assistance

provided by the Central government has been unevenly spread and thus has failed to bring about any noticeable

improvement in urban infrastructure. Keeping in view the shortcomings in the existing programmes and the

commitment given in the Common Minimum Programme of the UPA Government, the Central government has

drawn a comprehensive programme of the formulation of JNNURM to accelerate urban infrastructure development.

JNNURM is the first comprehensive planned approach and it is significantly different from earlier GOI initiatives,

although its stand on issues like commercialization, public and private sector involvement, regulatory reforms and

the focuses are similar. The mission aims to create ‗economically productive, efficient, equitable and responsive

cities‘. With the implementation of JNNURM policy, certain issues have been generated such as; can JNNURM

make Indian Cities ‗Magnets of Hope‘?

The focus on the very issue of whether the JNNURM would address the concern of the urban poor, their access to

shelter and basic services as without shelter, access to basic services is not possible. Is JNNURM is supposed to

convert mega and large cities into ―world class cities‖ and not necessarily serve the poor? JNNURM has a

compliance and also conformity for the urban poor. A large amount of funds, have been committed for this mission.

In itself, such a transformation of a city is agreeable, if it would benefit all or benefit some and not adversely affect

others. In retrospect to this, concerns that may arise are discussed. At present, the Master Plans or Development

Plan prepared under the Town Planning Act and the City Development Plan envisaged under JNNURM stand on

two independent pedestals with no relevance to each other. Moreover, a CDP does not have statutory backing.

JNNURM should attempt, through the reform package, to make the CDP flow from the Master Plan through a legal

tool. The major metros, in particular, are quite enthusiastic about NURM and many states have already prepared

CDPs for the cities covered under the mission. It was likely that not all the 63 cities listed would be covered and

only those with the capability to raise their own resources would come forward.

Even today, India‘s case is very different from that of the other countries; given that the institutional framework for

urban infrastructure development is so varied across the states that it cannot be generalized. There are too many

institutions; all with few functions, resulting in a poor state of urban infrastructure, huge finance requirements to

meet the infrastructure goals and no institution made responsible and accountable for the purpose. The problem is

compounded by the municipal governments having no other source of revenue but the property tax, and with 25 per

cent of the urban population below the poverty line; there are large sections for which even basic services are

unaffordable if given at cost. Urban infrastructure investments therefore delay significantly, and there is too much

of fragmentation of urban institutions in India for infrastructure delivery. The urban issues are complex and

multidimensional with involvement of three tiers of Government and other stakeholders. Whether the report

presented by Rakesh Mohan Committee, Master Plans or Development Plan prepared under the Town Planning Act

and the CDP envisaged under JNNURM under the GOI JNNURM policies, the biggest question is, how far have

we progressed? If all these have been parallel and along the same line as the recommendations given in 1996 and so

on, then what further improvements have been made in 15 years or 63 years of Independence? What is the present

situation? Where we are now and from where we go? The greater urgency has risen to address these crucial issues.

Background

Real urban planning is a relatively new concept. It gained popularity in

the mid-to-late 19th century, when it became obvious that there should be

some kind of plan or larger goals for the growth of big cities like New

York and Philadelphia. Before this time, cities very often grew as per

need, and the surrounding land was just swallowed up. London, Paris and

Tokyo - none of these world cities had much urban planning, and even

now, the addresses and streets in their older sections can be confusing even to natives. Urban planning takes all

aspects of a city into consideration. It includes plans for safety, aesthetics and common sense placement of

everything from houses to factories. Goals for attractive architecture for city buildings are put into place and

pleasing green spaces are planned. Good urban planning gets schools into the neighborhoods where they are

needed most, places hospitals in centralized locations, allows for growth and plans highways accordingly. Even

placing sewer systems and drainage systems is a necessary element of urban planning. When efficient urban

planning is used, cities are more attractive and serve their citizens to the best of their potential. Planning, also

called urban planning or city and regional planning, works to improve the welfare of people and their

communities by creating more convenient, equitable, healthful, efficient, and attractive places for present and

future generations. Good planning helps create communities that offer better choices for where and how people

live. Planning helps communities to envision their future. It helps them find the right balance of new

development and essential services, environmental protection, and innovative change.

Urban Planning – Data Components

What defines our city? How is the city arranged

spatially? How dynamic is the urban environment

changing over time? Where are traffic hot spots?

Where are climatologically and socially the best

neighbourhoods? How many people live there? Urban

planners need answers on these space-oriented

questions and many more. Remote sensing has the

unique capability to support decision-making with

spatial, quantitative data and information products on various topics, from the extraction of urban morphology

to the detection of urban growth, surface temperatures, to monitoring of traffic or assessment of population.

Urban planning covers under its gambit several disciplines like Community Development, Land Use & Code

Enforcement, Transportation Planning, Environmental/Natural Resources Planning, Economic Development,

Urban Design, Planning Management/Finance, Housing, Parks & Recreation and Historic Preservation. A

comprehensive plan can be arrived at with detailed studies on the following variety of datasets:

1. Land cover maps (1:25,000 to 1:100,000 and even better for city level) that are used to present land by

main usage of the areas that compose it.

2. The physical characteristics of a city including data relating to:

Relief configuration

Land type and aptitudes

Composition and structure of the subsoil

Hydrographic data

Climate and meteorological conditions

Data Availability

The availability and accessibility of these data sets is a grave problem faced by all planners. Adding to this is

the issue of standardisation of the data without which the data cannot be put to any fruitful use. The Natural

Resources Data Base (NRDB) an initiative of ISRO is a repository of thematic data sets at various scales.

NRDB is a collection of data sets on natural resources collected over past several years under NNRMS. It

consists of databases of spatial information created under NNRMS tied through common standards and

accessible through a common search engine over a secured network. The access to these databases has been

channelised through NNRMS portal http://www.nnrms.gov.in.

NRDB

The scope of NRDB is to organise and maintain a standardised GIS database of all the NNRMS spatial

information covering the entire country and position spatial data services from the database to serve the needs

of DOS users and NON-DOS users coming from government, business and citizens at large. The Major

Objectives accomplished are:

Facilitated evolution of a data exchange and distribution policy for NNRMS.

Evolved common procedures and design for organisation and maintenance of NR

database, using the NNRMS standards.

Facilitated Definition and implementation of procedures, processes and tools for data

quality vetting and database validation prior to incorporation into NRDB.

Defined and implemented procedures and tools for organising the in-coming data sets,

as per NRDB design structure, and populating the data servers.

Developed and implemented the tools for data services through NNRMS portal.

Developed and implemented tools for generating metadata.

Created a network of database servers using SPACENET.

Typical case Study: Allocating land for the NANO Plant

The Landuse map of Gujarat generated at 1:50,000 scale was examined. This map had broad classification with

details about agriculture, built up land, forest, grassland, grazing land, wastelands, wetlands, water bodies and

so on. The third level of classification showed the degraded grasslands/grazing lands which was then examined

for transportation networks and then allocated to the NANO plant. The figure below clearly depicts the optimal

use of the Landuse layer for setting up an industry that has proved to be economically viable and generating

employment to the local people.

Better planning leads to better and sustained services. This calls for availability of multifaceted data at multiple

scales for addressing planning at all levels right upto regional or state level.

Urban Services:

The Ministry of Urban Development has emphasised that that

India‘s economic growth momentum cannot be sustained if

urbanization is not actively facilitated nor can urban poverty be

effectively addressed if the needs of the urban poor are isolated

from the broader challenges of managing urbanization. The

infrastructural services like water supply, sewerage, solid waste

management, storm water drains, urban roads, urban transport,

street lighting, and traffic support infrastructure etc. are the major

challenges and opportunities emerging in the urban areas of India.

NRDB can play a major role in accepting and resolving these

challenges by enriching it with data at better scales and better

receptivity.

Introduction

In the fast developing countries like India, there is a mass migration of people from rural to urban and also from

smaller to bigger urban areas such as metropolises like Delhi, Bangalore, and Mumbai etc. The urban sprawl

resulting due to increase in population creates a huge demand on land and other limited resources. The

phenomena of this accelerated urbanization and population growth impacts environment primarily through the

growth of dense and unplanned residential areas, environmental pollution, non-availability of services, use of

natural resources and production of wastes and growth of slums (Mohan, 2010). Delhi is one of the many

megacities struggling with rapid urbanization and gigantic levels of pollution from industrial, residential, and

transportation sources. Due to urbanization process mass scale deforestation, the reduction in the green cover,

the increase in the built-up land, the use of materials like concrete, asphalt, tar, etc. comes into picture which

significantly alters the energy balance of the urban areas often causing the temperature to reach relatively

higher value than its surroundings. This phenomenon is also known as Urban Heat Island. It is also believed

that air pollutants, in particular aerosols, can absorb and re-radiate long wave radiation and inhibit the

corresponding radiative surface cooling producing a pseudo-green house effect and contribute towards the

urban heat island phenomenon in urbanized cities. Recent technological advances made in the domain of spatial

technology resulted into considerable impact on planning activities. This domain of planning is of prime

importance for a country like India with varied geographic patterns, cultural activities etc.

Based on the above background, the impact studies of the dynamical city development are demonstrated here

based on the work carried out for the megacity Delhi in the following areas:

(i) Land- use land cover change detection by remote sensing techniques,

(ii) Temperature trends (as proxy to urbanization) and urban heat island studies,

(iii) Air Quality Assessment.

Landcover Dynamics and Change Detection Analysis by using Remote Sensing

(Mohan, 2010; Mohan et al 2011c)

A study was undertaken to identify the spatio-temporal pattern of landuse-landcover (LULC) changes which

occurred in Delhi using satellite images (LISS III and LISS IV) periodically from 1997 to 2008 (Mohan, 2010;

Mohan et al 2011c). The satellite imageries were used with supervised classification for landuse landcover

analysis. The imagery is classified into total 10 classes which are dense built-up, medium dense built-up, less

dense built-up, crop land, fallow land, forest, scrub land, sandy areas, deep water body and shallow water body.

Figure 1 (next page) shows the land-cover changes that occurred during this period.

There is an overall net increase of 251.18 km2 (16.87 %) in built–up area. On the other hand there is a decrease

in agricultural area of 146.75 km2 by combining the decrease in crop and fallow land. There is another

significant decrease in wasteland by 80.62 km2 by combining scrub-land and sandy areas. Area covered by

water bodies reduced from 58.26 km2 in 1997 to 27.43 km

2 in 2008 which is about 52.9% decrease in a ten year

period. Thus increase in built-up area in the city has been on the expense of majorly from the agricultural and

waste land together with the shrinking water bodies. As the city developed, the built-up category replaced most

of the land classes like sandy areas, fallow land and scrub land. The changes in LU-LC classes are more from

population pressure as the population growth is very high in Delhi. It is highly recommended to restore the

water-bodies in the city.

Temperature trends (as proxy to urbanization) and urban heat island studies

(a) Temperature trends in Delhi (Mohan et al, 2011b)

The local temperature is one of the major climatic elements to record the changes in the atmospheric

environment brought about by industrialization, increasing population and massive urbanization. In this study,

annual and seasonal temperature trends and anomalies for maximum, minimum and mean temperatures were

studied for four meteorological stations of the National Capital Region (NCR) of India namely Safdarjung,

Palam, Gurgaon and Rohtak for the past few decades (Mohan et al, 2011b). A consistent increasing trend was

seen in the annual mean minimum temperatures indicating an overall warming trend over the NCR especially

after 1990. This study reiterates the fact that increasing warming trends in the night-time temperatures reflect

the contribution of changing land-use patterns and additional anthropogenic heat. The association of increasing

temperatures with urbanization was further strengthened by the trends of differences in annual mean minimum

temperature of the two stations within the city namely Safdarjung and Palam (Figure 2). During the 1968-1985,

it was Safdarjung which had higher night time temperatures because it was more built up than Palam. After

2000, the two stations had almost the same annual mean minimum temperatures. In subsequent years as Palam

had also urbanized as most of the other areas in the city and with coming up of the Indira Gandhi International

(IGI) Airport, the differences between the two stations have diminished.

(b) Urban Heat Island Intensities observed over Delhi (Mohan et al, 2009b)

A study of ambient temperatures of Delhi for about two and a half years (2006-2008) indicated that a major

portion of the entire data (~ 58.7 %) fell under warm and uncomfortably hot categories (Mohan and Bhati,

2009a). These ‗Uncomfortable‘ conditions lead to more usage of air conditioners which in turn leads to more

heat emissions. An urban heat island is defined as a metropolitan area that is significantly warmer than a

comparatively rural or lesser developed area in vicinity. To understand the prevalence of urban heat island in

the city, a study was conducted to measure round the clock temperatures across the National Capital Region of

Delhi at about 30 sites which were representative of different LULC like Urban Built Up areas, Green Areas,

Open Areas and Riverside Areas (Mohan et al, 2009b). The urban heat island intensity (UHI), or the inter-

spatial temperature difference was found to be as high as 8.3 °C at locations like Sitaram Bazar and Connaught

Place when compared with green areas like Sanjay Van or Buddha Jayanti Park. The top three areas with

highest temperatures were found to be CP, Sitaram Bazar and Bhikaji Cama Place. Other pockets with

reasonably high UHI were residential or mixed use namely Noida, Dwarka, Janakpuri, Kaushambi, Adarsh

Nagar etc. In other words, densely populated areas or highly built up areas form the core UHI zones. Figure 3

displays an excerpt of the results of the study published in The Hindustan Times dated 26 September 2009.

Figure 3: Urban Heat Island zones in Delhi (The Hindustan Times dated 26 September 2009)

Air Quality Assessment (Mohan et al, 2011a)

Rapid urbanization of Delhi over the past few decades has also made it one of the most polluted cities in the

country. In particular, air quality of Delhi is of major concern among many regulatory policies. Studies have

indicated relationships between pollutants such as particulate matter and respiratory and cardiovascular

morbidity as well as mortality. Air quality models and exposure assessment studies provide a tool to understand

the implications of pollutant emissions and aid in deciding control and management strategies. With this

consideration, study was undertaken to evaluates the performance of a regulatory air quality model AERMOD

(version 07 026) for modelling concentrations of particulate matter in Delhi for the year 2004 and results

applied to undertake exposure assessment in terms of mortality response for two hypothetical scenarios as

shown in Table 1 (Mohan et al, 2011a).

Remote sensing technology, meteorological and air quality measurements and modeling tools can be effectively

used to assess dynamical urbanization process of the cities and plan appropriate control strategies as illustrated

with the above case studies.

Geomatics is receiving growing attention in solving spatial decision problems for urban planning. Many

planning tasks such as industrial site selection or site evaluation require consideration of a comprehensive set of

decision parameters and preferences related to spatial and non-spatial in nature. It also requires integration and

manipulation of these data sets with respect to a set of suitable criterion for setting up industrial park.

Moreover, the need for site planners to attract economic activity to their locale becomes an ever increasing

priority for infrastructure development. In this context M/s Gujarat Infrastructure Limited (GIL), Ahmedabad,

an agency responsible for siting industrial areas and Space Applications Centre, Ahmedabad jointly worked for

the purpose of identifying a suitable site using geomatics for setting up an industrial park in and around Khatrej

area. The study was carried out during 1996-97. This study demonstrates the potential offered by the integration

of the tools of image processing and Geographic Information System (GIS) for industrial site selection and

infrastructure development.

Introduction

Many planning tasks such as industrial site selection or site evaluation require consideration of a

comprehensive set of decision parameters and preferences related to spatial and non-spatial in nature. It also

requires integration and manipulation of these data sets with respect to a set of suitable criterion for setting up

industrial parks. Moreover, the need for site planners to attract economic activity to their locale becomes an

(GIL), Ahmedabad, an agency responsible for siting industrial areas and SAC jointly worked for the purpose of

identifying a suitable site using RS and GIS technique for setting up an industrial park in and around Khatrej

area, Gujarat. The issue of industrial site selection is a classic theme of locational theory. The site selection

process resembles a real estate transaction in which industrial site agents deal directly with a client to find a

suitable site that meets a series of locational and site specific criterion. This process is an iterative one in which

the client has a set of desirable site characteristics that include size, cost, utilities, existing built-up lands and

land use/land cover pattern that can be coupled with a series of desired locational constraints. This can be

developed as multiple knowledge based spatial decision support system by creating link between GIS and

Image processing techniques.

Objectives

To prepare urban land use map on 1:12,500 scale using IRS-1C merged products depicting level-II urban

land use information.

To prepare thematic maps viz. surface water bodies map, slope map, soil map, flood and erosion hazard

maps, hydrogeomorphological map, ground water

prospect map, and transportation network map for

the purpose of urban suitability analysis.

To carry out site selection analysis based on the

physical parameters towards siting a suitable area for

industrial park.

Study Area

The study area is located in north-west part of

Ahmedabad district. The area is between Kalol and

Ahmedabad cities which comprises 44 villages (full or

part) and covers an area of about 27920 ha (Fig. 1).

Total population of the area was 84271 (1991 census). Physiographically, it has a flat terrain with gentle to very

gentle slopes. The significant physiographic feature in this area is the undulating terrain with small to big

mounds with an elevation of about 80 m. The soil in this region is generally a light sandy loam with deep to

very deep soils. There is a big industrial site near Santej town, in which different type of small industries like

polycot, polyplasts, filtration, agro-base industries exist.

4. Methodology

The overall methodology adopted for site selection analysis is presented in Fig. 2 and the details are as under.

Spatial database was created for entire study area. The data

base for the integrated development has basically two

components. i.e. Spatial and Non- Spatial data. Arc/Info GIS

software has been employed as the main tool to design,

creation, organisation, analyze and generation of cartographic

outputs. The spatial data is mainly from Remote Sensing data

and ancillary sources. IRS 1C LISS-III and PAN data of

1996-97 have been used for interpretation of various themes.

Survey of India topographic maps on 1:50,000 scales were

also referred for creation of some of the thematic maps.

Census 1971, 1981 and 1991 data for the study area was

collected and integrated with spatial database. Fig.2: Methodology adopted for site selection

Extensive GPS survey was carried out to collect ground control points (GCP‘s) in the study area. IRS LISS-III

and PAN data were geometrically corrected using GCP's. Merged data products were generated by taking

intensity from Panchromatic data, hue and saturation from LISS-III data. Various enhanced techniques have

been applied to improve the contrast between the features on this merged data. The products generated using

Laplacian filtering technique (edge enhancement

operation) was selected for the study employing visual

interpretation techniques. A ground survey was carried

out in the entire study area and the information obtained

from the preliminary interpretation has been correlated

with the actual thematic information on ground.

Land use/cover map: Information on land use/ land

cover, especially the extent and spatial distribution is a

prerequisite for the siting analysis. The land use/cover

information help in formulation of policies and program-

mes for urban development. The urban land use/land

cover database was prepared for the entire study area

(Fig. 3). Fig.3: Land use / Land cover map

The area is between Kalol and Ahmedabad cities which comprises 44 villages and covers an area of about

27920 ha. 52 per cent area is under fallow land category. About 12 per cent land is under wasteland mainly

with or without scrubs. Details are summarized in Table-1. Graphical distribution of different land use classes

is shown below.

studied and a layer has been created. Each polygon has the information related to the association of soil series.

From these soil types, soil depth and soil texture have been separated out and the maps have been prepared

separately. The extent and spatial distribution of soil depth, soil texture play an important role in urban land use

suitability analysis and selection of industrial site.

Slope and aspect: Slope map was generated using elevation information derived from SOI topographical maps

and TIN (Triangulated Irregular Network) module of

Arc/Info. A sampling method was used to extract

representative points to build a surface model that

approximates the actual surface. In all about 100 points

were selected representing the plain areas, undulating

terrain, depressions etc. in the entire study area and as

well as from the adjoining 5 Km buffer areas. A point

layer has been generated for the preparation of percent

slope map and surface views. The slope map was

prepared using both TIN and LATTICE methods. From

this slope map, 1-m contour information has been

derived for the entire study area. 1 m contour interval

map with proposed site is shown in Fig. 4. Fig. 4: contour map (1 m interval)

Information on slope and aspect of terrain in the study area are vital in determining the land suitable for

different types of land uses. This information is also useful for drainage schemes. It is found that most of areas

are under category of very gentle to gentle slope. However, it has been observed that two slope classes only are

present in the entire study area. A few elevated areas are observed in the study area, which are called 'tekras'. A

depression zone is present near Thol Lake. But mostly the slope in the study area is less than 3 percent; hence

the area can be treated as flat area with very less significance of slope.

Flood hazard map: Identification of flood prone area plays a major role in the site selection process. The low

lying areas, marshy/wetlands are particularly not suitable for urban development. The low lying areas are

highly subjected to floods and are normally not used for construction purpose. Hence, a flood hazard map of the

study area has been prepared using multi-date RS data. This map has been finalized in conjunction with the

slope and 1-meter contour maps prepared using GIS techniques. From this map, the areas under different flood

zones are identified. These areas have to be conserved and construction activity should not to be allowed.

Drainage pattern and surface water bodies: Drainage pattern and surface water bodies have been studied

using both pre-monsoon and post-monsoon satellite data. The water spread of the surface water bodies were

delineated mainly from the post monsoon data. There are 28 village tanks/ponds exists in and around study

area. The most important surface water body in the study area is Thol Lake.

Settlement and transportation network map: The road network is one of the important parameters in

identifying the areas for urban development as it provides linkages between the settlements. The entire study

area has been classified under three types of roads viz. major roads, minor roads and kutcha roads. This map

was prepared using satellite data.

Village demography and amenities: Census and amenity data pertaining to 1971-91 censuses has been

collected. The population and its distribution in different parts of study area is an important input in planning

for the region. Thus the population of each settlement has been studied and used for the suitability analysis.

Analysis carried out to derive various demography parameters like population density, literacy, agricultural

workers, sex ratio etc.

Data Analysis and Results

The site selection comprised two phases viz. I) Search for a suitable area based on physical characteristics of

the terrain and ii) A conditional search. The physical suitability search phase refers to finding areas that match

the physical, environmental or geographic conditions. The conditional search phase identifies a set of preferred

conditions that are applied to the composite coverage. In the present study, both physical and conditional

searches were used for site selection analysis.

Search on the basis of physical parameters

Identification of suitable land for urban development is one of the critical issues of planning. The suitability of

the land for urban development is not only based on a set of physical parameters but also very much on the

economic factors. The cumulative effect of these factors determine the degree of suitability and also helps in

further categorising of the land into different orders of development. The assessment of the physical parameters

of the land is possible by analysing various thematic layers which are very much amenable to GIS analysis. As

against this, the economic pressures on urban land are very much difficult to be specified and used for analysis.

However the assessment of physical parameters gives an identification of the limitations of the land for urban

development. The concept of limitation is derived from the quality of the land. For example, if the slope is high

the limitation it offers is more than a land which has gentle slopes or a flat terrain. Practically, this would mean

that the development of the high slope land would require considerable inputs (finance, manpower, materials,

time etc.) and thus may be less suitable as against the flat land where the inputs required are considerably less.

This concept is true for all the land parameters that are assessed. Identification of suitable areas for urban

development is, therefore, one of the critical issues in the urban planning. The land suitability not only is based

on a set of physical parameters but also very much on the economic factors. The composite effect of these

parameters determines the degree of suitability and also helps in further categorising the land into different

classes of development. Moreover, the process of suitability assessment is very much dependent upon the

prevalent conditions such as pressure on land. If the pressure on land is too high, it may give rise to a high order

of speculation and may lead to development of land which is otherwise not suitable from suitability point of

view. This clearly states that the level of inputs would be high due to the market forces. It is in this context, the

suitability analysis attempted in this study must be viewed as a basic "Priortisation of land for urban

development".

In this particular study, nine important physical parameters are considered for the analysis. They are i) Soil

depth, ii) Soil texture, iii) Slope, iv) Land use/cover, v) Ground water prospects, vi) Flood hazard, vii) Erosion

hazard, viii) Surface water bodies, and ix) Distance from road which are mostly accepted by Urban planners.

The inventory of these parameters has been carried out using RS and GIS techniques. The details with respect

to each parameter are already stated earlier. The physical parameters of the land were analysed in GIS

environment using a weighted index model (Revised Development Plan of Ahmedabad Urban Development

Authority, 1997). A composite layer has been generated by integrating nine thematic layers using union process

in GIS environment. The composite layer generated by integrating all the nine layers has been termed as "Com-

posite Urban Land Development Unit (CULDU)" layer. The CULDU layer has composite units and each unit

has the characteristics of all the parameters considered for the suitability analysis. All the units have been

assigned weightages derived using eigen vector method (Ahmedabad Urban Development Authority Report,

1997). The ranks also have been assigned to all the units by creating a separate field. Thus, each unit in the

composite layer is associated with both weightage and rank. A weighted index analysis has been done to

identify CULDU‘s for construction purpose and conservation activities.

Search on the basis of conditions

The conditional search phase identifies a set of preferred

conditions that are applied to the composite layer. Initially

urban land use suitability criteria have been applied on the

composite layer to identify the areas suitable for urbanisation

and the areas to be conserved. Then, conditional search

criteria were applied on the areas suitable for urbanisation to

arrive at a suitable site for industries in the study area. These

were

preferably it should be a wasteland

the site should have deep to very deep soils with loamy

texture Fig. 5: Proposed sites for industries

the site should not have any flood and erosion hazards

preferably it should be nearer to existing roads and

the site should not encroach settlements, temples,

defense establishments, air force station, high tension

electric lines, gas stations etc.

Using above mentioned criteria a map of three sites suitable

for construction has been prepared (Fig. 5). The conditional

search mentioned above has been applied on these three sites

suitable for industrialisation. Finally an area of about 2781

ha has been earmarked for the industrial park to be set up in

and around Khatrej without disturbing the existing

settlements, temples, defense installations etc. The land use / land cover map of proposed site is shown in

Fig. 6. This industrial site will have residential, recreational, transportation network, public and semi-public

uses apart from the main industrial site meant for Arvind Polycots.

Conclusions

In all there are 44 settlements in the entire study area with Borisana having highest population of 5899

persons and Ganpatpura with the lowest population of 180. However, in the final site identified for

industrial siting has only four settlements viz. Bhimasan, Hazipur, Kaptanpura, and Karoli. Khatrej and

Santej are the settlements which are going through the phase of rapid development in this area.

The wastelands in the study area are mostly tekras with or without scrub lands. The water-logged areas

have also been observed in the study area located near Thol Lake.

The groundwater prospect in the study area is omnipresent. The aquifer system comprises both unconfined

as well as confined aquifers. The confined system is the main source of agricultural, industrial and domestic

water demand. The main limiting factor of potable water is the quality of groundwater in some areas. In

Alluvial plain (vegetated), at most places groundwater is drawn from deeper aquifers and provides usable

quality of groundwater with some exceptions. A systematic survey involving collection of groundwater

samples for quality analysis is required to assess the potability of the water precisely.

The soils in the study area are deep to very deep, moderately well drained, calcareous, fine soils on very

gently sloping flood plain with slight erosion, slight salinity and are associated with deep, moderately well

drained, calcareous, fine soils with slight erosion and slight salinity. These soils do not pose any problem

for the purposes of industrial development.

It has been observed that two slope classes are present in the entire study area. However, it has been

observed that the slope in the study area is mostly very gentle to gentle, from North to South. A few

undulating mounds have been observed which are called 'tekras' having terrain heights up to 80 m. A

depression zone has also been spotted near Thol Lake. But mostly the slope in the study area is less than 3

percent; hence the area can be treated as flat area and is good for industrial development.

The most important surface water body in the Study area is the Thol Lake. There are no major rivers or

stream in this area. However it has been found that all the village settlements are associated with tank/lakes.

The flood hazard has been observed only in some areas near Thol Lake. Apart from this, there is no flood

hazard in the entire study area.

All the village settlements have been linked with all weather roads which are motorable in all seasons.

The final site selected for setting up the industry in this area has an area of about 2781 ha. Majority of the

area is under fallow and wasteland category. The site does not have any hazards related to water logging,

erosion etc. The site is not encroaching any important land marks such as temples, high tension lines, gas

stations, electric stations, defense installations etc.
