Geospatial Technology

This project focuses on leveraging geospatial technology to streamline the process of population census in Indonesia, particularly by enhancing data collection efficiency through the integration of digital maps. The initiative includes activities such as preparing census block maps, optimizing digital maps for enumerator use, and geotagging buildings and landmarks. The project aims to improve accuracy and streamline data dissemination through the utilization of geospatial tools combined with mobile applications. To address existing challenges related to data integration and system upgrades, proposed solutions involve automating data transactions, developing standardized attributes, and creating a mobile application to aid enumerators in navigating their assigned areas.

  1. Geospatial Technology Indonesia Population Census 2020

  2. Indonesia Statistical Area Province Municipal District Census Block Village

  3. Geospatial for Population Census2010 vs 2020 • Using sketch maps to aid enumerator to identify Census Block; • Enhance quality of digital maps; • Delineating Census Block boundary based on digital images (satellite imagery); • Digital images were limited. • Overlaying digital maps and Google Road to produce paper map; • Using digital maps to aid enumerator to identify Census Block; • Embedding the digital maps in a mobile application; • Collecting Geotag photos of buildings in Census Block (CAPI). 2010 2020

  4. Census Block Map2010 & 2020 2010 2020

  5. The Integration of Census Activity and Geospatial Pre enumeration • Preparation of Census Block Maps. 2018-2019 2020 2021 Enumeration • Optimization of digital maps to identify the Census Block using mobile application; • Collecting of building locations. Post Enumeration • Developing of web GIS for dissemination. • Utilizing digital maps for other census and survey activities.

  6. Activity in 2018 • Updating digital map based on digital images (Google satellite, SPOT, etc.) and sketch maps; • Establishing Ground truth position and boundary of sample census blocks; • Overlaying between updated digital map and Google Street to produce paper maps.

  7. Activity in 2019 Process: • Establishing Ground truth position and boundary of all census blocks; • Counting of census buildings in each census block; • Geotaging landmarks (Census Block POI and infrastructure); • Updating digital map, delineating census block boundaries based on ground truth; • Overlaying between updated digital map and Google Street to produce paper maps. Output: • Updated digital map; • Geotagged photos of Census Block POI; • Geotagged photos of infrastructure landmark; • Paper maps of Census Block.

  8. Developed Applications Related to Geospatial

  9. Challenges • The applications are not integrated • The applications use different Databases (silo); • Distribution of Census Block Master to each application by export/import manually; • CAPI application is not support for digital map.

  10. Propose Solutions • Upgrading the system in order to integrate data transactions; • Developing a mechanism to automate proses of data integration; • Developing a mobile application for geospatial data (digital map), as an aid for the enumerator to identify his/her area; • Developing standardization of attributes in order to simplify the updating process.
