1. Introduction

Census of Population and

Housing (CPH)

Census of Agriculture and

Fisheries (CAF)

Census of Philippine Business

and Industry (CPBI)

➢2015 Global Adult Tobacco Survey

➢Labor Force Survey (LFS)

➢2017 National Demographic and

Health Surveys (NDHS)

➢2017 Listing of Farm Households

(LFH)

Computer-assisted personal interviewing (CAPI)

➢Survey on Retail Prices for the Generation of

CPI and other Price Indices

1. Introduction

➢2018 Updating of List of

Establishments (ULE)

➢value of location or the application of “science

of where”

➢In 2016, the Environmental Systems

Research Institute (ESRI) introduced

the potential applications of modern

GIS platform in the statistical business

processes

➢ integration of statistical and geospatial

information

Geographic Information System (GIS)

2.The GIS-Based Data Collection

Digitized Census Maps

(Enumeration Area

Maps)

Geo-tagged Buildings

Generation of geodatabase

that contains both geospatial

information (i.e., x, y

coordinates) and census

data

Listing and Enumeration

3.The 5-year Rolling Program to Enhance the

Digitized Census Maps

Field validation of

MSF for Household-

Based Surveys

Conduct of tablet-aided geo-

tagging of buildings to

develop digitized building footprints from 2017 to 2019

Conduct of 2020

CPH using tablet device

2016 2017 2018 2019 2020

Technology-aided EA

delineation from digitized census maps

4.The Census/Survey Workflow Using GIS Technology

The GIS-Based Platform for the 2020 Census of Population and Housing

(Majority CAPI-based Data Collection Mode)

4.The Census/Survey Workflow Using GIS Technology

The GIS-Based Platform for the 2020 Census of Population and Housing

(Majority PAPI-based Data Collection Mode)

5. Geo-tagging of BuildingsVector data points are created by marking or tagging

building structures as points in the digitized map

simultaneously integrating attributes such as address

of building, and building type, among others

2017

24,853 EAs

2018

31,000 EAs

2019

37,000 EAs

the geo-tagged points and digital building

footprints can be used to develop a map-based

sampling frame or geo-enabled master sample

frame (GMSF)


Geo-tagged buildings in Barangay Tuhel (Poblacion), Ivana, Batanes



Density-Based Clustering of geo-tagged buildings in Basco, Batanes













GIS-Based Operations Dashboard



The enumerator will

rely on the printed

census enumeration

area (EA) maps and

digitized block maps

incorporating the

printed Building Serial Number (BSN)

Printed Block Map with Building Serial Number of

Geo-tagged Buildings


In this process,

the enumerator

will indicate in

the listing

booklet (CPH

Form 1) the

Geo-point BSN

of geo-tagged building


The geo-point (i.e., x, y

coordinates) of the

building can be

integrated with census

data from processed

CPH Form 2 or CPH

Form 3 using the

corresponding Geo-

tagged building BSN

listed in the CPH Form 1

8. Post-Enumeration/Dissemination

➢ Surveys/census data can be

stored and managed using the

Geodatabase

➢ that will allow application of more

dynamic dissemination

techniques

➢ Data which has geographical or

spatial aspect, can be presented

differently using story maps, web

maps, web apps and other map-

based data visualization

9. Conduct of Pretesting for the map-based data Collection

• Pretest 1: Manila and San Juan (September 2017)

• Pretest 2: Palawan and Guimaras (October 2017)

• Pretest 3: Pampanga (November 2017)

• Pretest 4: Bulacan (April 2018)

• Pretest 5: Batangas (June 2018)

• Mini Pilot Census: Janiuay, Iloilo (October 2018)

• Pilot Census in Eight (8) Selected Areas in the

Philippines (20 May to 17 June 2019)

Map-based data Collection using CAPI

• Pretest 6: Rodriguez, Rizal (19 September 2019)

Map-based data Collection using PAPI

10. Recommendations

1. To embrace innovative and

transformative solutions through

full implementation of GIS

Technology, the GIS Enterprise,

and the enhanced GIS-based

Survey Apps, Map Data Collector

Apps, and GIS-based monitoring

dashboard as the front end of

tablet-aided data collection.

2. To consider a long-term

investment in GIS

technology that can be

fully applied in our

statistical business

processes.

10. Recommendations

3. To have a continuing capacity

development plan of PSA

Personnel by conducting a

series of GIS trainings,

developing GIS-based projects,

and participating in local and

international fora/ meeting

concerning GIS technology

development.
