Regional Workshop on the Use of Electronic Data Collection Technology in

Population and Housing Censuses

UN ESCAP, Bangkok

Use of GIS/GPS in Support of the Philippines

2020 Census of Population and Housing



Outline of the Presentation

• Initiatives of Using GIS in Household Surveys

• GIS Technology Rolling Program for Census Map

Updating

• The 2020 CPH Workflow with GIS Technology





The Philippine Statistics Authority (PSA)

aims to continue the modernization of its

statistical processes and survey

operations including the conduct of the

2020 Census of Population and Housing

(CPH) using GISTechnology

Background





Selected surveys that make use of

tablets with GPS capability to

acquire sample households’

coordinates.

Data are sent to the CO server.

These households can be viewed on

map with their corresponding status

of interview

2020 CPHTo fully utilize the application of

GIS Technology in preparation for

the modernization of the PSA

2020 Census workflows, the PSA

developed a 5-year rolling

program (from 2016 to 2020) to

update and enhance GIS-based

digitized census maps for the

entire country.





The 5-year rolling program

intends to prepare the PSA

for the application of

geospatial analysis and

intelligent data visualization

of using dynamic digitized

maps by 2020.

2020 CPH





1. Validation of Master Sample Frame (MSF) for

Household-Based Surveys through

• verification of selected Primary Sampling Units

(PSUs) area boundaries (Barangays/EAs)

• actual location (using GPS waypoints) of

Secondary Sampling Unit (SSU) (housing units)

within the PSU. (2016)

2. Tablet-aided geo-tagging of buildings to develop digitized

building footprints (2017 to 2019)

3. Technology-aided EA delineation (2019)

4. Conduct of 2020 CPH using Tablet device incorporating

the digitized building footprints to link geo-referenced

spatial information with census statistical information

(2020)





In 2016, the Environmental

Systems Research Institute

(ESRI) introduced the ArcGIS

online platform to the PSA

through a location value

assessment (LVA) exercise in

an effort to help the PSA to

improve the census/survey

data collection.

The 2020 CPH Workflow using

GIS Technology





In 2017, ESRI partnered with

PSA on the use of license

ArcGIS online system at no

cost in testing the system’s

capability of handling census

operations from preparatory

up to the dissemination of

results.


GIS Technology






GIS TechnologyIn the same year (2017), the PSA conducted a series of pretests for

the 2020 CPH to simulate the use of GIS Technology in census

operations using the ESRI’s ArcGIS Survey 123 and ArcGIS Collector

for Geo-tagging of buildings.





The 2020 CPH Workflow using GIS

Technology






GIS TechnologyArcGIS Collector in the geo-tagging and

updating of GIS-based census maps

ArcGIS Desktop will be used for GIS-based

map preparation including census

enumeration area (EA) delineation.

The PSA is currently using Qfield freeware

android tablet application for field operation,

and QGIS desktop freeware application for

GIS-based map preparations.






GIS Technology

At the data collection stage, the ESRI proposed

the use of ArcGIS Survey 123 CAPI technology

with spatial integration that would link geospatial

information with census information during the

actual field operations. The geospatial

information will be taken from the geo-tagged

buildings/housing units that is already loaded in

the tablet device.

The ESRI also proposed the ArcGIS Workforce to automate the workload

allocation process to assign EA to the enumerators using supervisor’s

dashboard.






GIS Technology

At the post-enumeration stage, the

ESRI proposed the use of ArcGIS

Desktop/Pro to do geospatial

analysis and augment dynamic

maps in the information

dissemination of 2020 CPH results

that can be shared online using

ArcGIS story map, Open data and

other GIS-based resources using

the ArcGIS online platform.
