Sudan is the largest country in Africa. It consists of 25 states

with a wide diversity in culture, custom and nature.

It is also a very resourceful country with a lot of potentiality.

Proper planning is required for distribution of essential services

assessing demographic scenarios and demand.

Back ground .

Census is an operation that collects, processes, disseminates

statistical data and analyzes the distribution of population, social,economic data

Here we endeavour to show an example of a rural area by

representing all the data on map and showing all available basicservices like water source, education, social services and general

services etc.

Development activities of the government and the most of statistics

and demographic study may be supported by GIS technology

Introduction:


5/16

Geographical Information System the technology that lets us the

opportunity to capture, store, manage, process and analyze the

spatial data and simultaneously lets linking with other attributedatabases

GIS represent the inventory of resources and their distribution

and, provide the decision makers the idea of optimum resourceallocation

GIS may help the planners, researchers, and decision makers

with spatial features and database support in proper planning

The General objective of this paper is to study the needs based on the

demographic scenario by creating an information system of spatial and census

database for all rural areas in Sudan

The specific objective of the study:

1. Build database for rural area and update it dynamically

2. Use data for international comparison and follow up with the goal of

MDGs.

3. Use of GIS system to data capture, view, verify, retrieve, query and analyse

rural area

4. Data retrieve and query of any services through attribute data

5. Reduce the time to find out any statistical or demographic data withrespective maps

Objective of study:


7/16

Methodology includes creating a strong information system to connect

geographical data with census attribute data

We depend on the data which is collected from the field for census

preparation by using the GPS (global positioning system) and download

these data to the computer and convert it to ARC GIS 9.2 compatible format

(*.shp file)

Then do edit, georeference, and other necessary process to create needed

layer

Enter administrative geocodes to the attribute tables for future linking withcensus attribute database

Method and Material :


8/16

For this study we depended on pre-census (2008) GPS (Garmin

60cs ) data and the data taken in the following method:

Village boundaries are drawn by tracking with GPS andrepresented as polygon shape and

All available services (educational sites, healthcare facilities, water

sources inside it.

First we made classification for all services and assign unique

symbol. All location of services is represented as point.

Available data:


9/16

Below is the summary is show that can process these data:

Verifying all the data captured by the GPS, by comparing it with the field manuscript

form.

Downloading data from the GPS to computer and transfer it to shape file format to

store it according to geographical boundary (region, state, locality, administrate unit,

village)

transfer all data to ARC GIS 9.2 program and do all operation like (editing, cleaning,

correction, projection, rectifying)

Transfer all services point according to the type of symbol and represent it as point

layer

represent all the boundary of village as polygon.

All boundaries and services are arranged systematically

Data processing:


10/16

We prepared map (Fig-1 to fig-5 shown below) from the spatial

data where respective services are found. It can be linked with

census attribute data and make different assessment dependingon demographic data.

may be so many demographic themes upon which such kind of

GIS analysis can be done and decision makers can do their job

based on these thematic presentations.
