1 Use of GIS/GPS in Support of the Philippines 2020 Census of Population and Housing Regional Workshop on the Use of Electronic Data Collection Technology in Population and Housing Censuses UN ESCAP, Bangkok January 24-26, 2018

2 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

3 Background The (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

4 Initiatives for HH surveys 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

7 2020 CPH To 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.

8 2020 CPH 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.

9 The GIS Technology-based Rolling Program for Census Maps Updating 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)

10 The GIS Technology-based Rolling Program for Census Maps Updating 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)

11 The 2020 CPH Workflow using 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. GIS Technology

12 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.

13 The 2020 CPH Workflow using GIS Technology In 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.

14 The 2020 CPH Workflow using GIS Technology

15 The 2020 CPH Workflow using GIS Technology ArcGIS 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.

16 The 2020 CPH Workflow using 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.

17 The 2020 CPH Workflow using 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.
