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)
5. Geo-tagging of Buildings
Geo-tagged buildings in Barangay Tuhel (Poblacion), Ivana, Batanes

7. Map-Based Data Collection Using PAPI
7. Map-Based Data Collection Using PAPI
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
7. Map-Based Data Collection Using PAPI
In this process,
the enumerator
will indicate in
the listing
booklet (CPH
Form 1) the
Geo-point BSN
of geo-tagged building
7. Map-Based Data Collection Using PAPI
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.
