By accessing, browsing, or using the PH Barangay Downloader web application (hereinafter referred to as the "Application"), you acknowledge that you have read, understood, and agree to be legally bound by these Terms of Service ("Terms") and by our Privacy Policy, which is incorporated herein by reference. If you do not agree with any provision of these Terms, you must immediately cease using the Application. These Terms apply to all visitors, users, and any other persons who access or use the Application.
The PH Barangay Downloader is a free, open-access, browser-based interactive Geographic Information System (GIS) application developed and maintained by Zenterra Systems Solutions. It serves as a general-purpose geospatial data downloader for the Philippines, centralizing and simplifying access to a variety of open-source datasets through a single interactive interface.
The developer does not own or produce the datasets available through the Application. All datasets are compiled from publicly accessible government servers, institutional platforms, and other authorized open-data sources. Current datasets include Philippine administrative boundaries (ADM0 through ADM3/ADM4), hazard overlay layers, and additional geospatial data as the platform expands. Users can interact with a 3D globe visualization powered by MapLibre GL, browse and select data layers, and download geospatial files in their choice of open formats.
All data processing — including format conversion, file generation, and downloads — occurs entirely within the user's web browser. No data is uploaded to, stored on, or processed by any external server operated by the developer.
The Application aggregates and presents geospatial data compiled from publicly accessible government servers, institutional platforms, and other authorized open-data sources. The developer does not own or produce any of the underlying datasets. All datasets remain the exclusive intellectual property of their respective source organizations. The Application's role is solely to centralize and simplify access to these open-source datasets through a single interactive interface.
All data available through this Application is open-source. Any selling, commercialization, or monetization of downloaded files is strictly prohibited by the original data owners and governing authorities. Current data sources include, but are not limited to:
Administrative Boundary Data
Philippine administrative boundary geometries (ADM0 through ADM3/ADM4) are sourced from the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) via the Humanitarian Data Exchange (HDX) platform. All geometries are encoded in the geographic coordinate reference system CRS84 / EPSG:4326 (WGS 84, longitude/latitude).
Hazard Layer Data
Hazard overlay layers are sourced from Project NOAH(Nationwide Operational Assessment of Hazards), a program of the University of the Philippines Resilience Institute (UPRI). These datasets are produced for disaster risk reduction and public awareness.
Additional Datasets
As the platform expands, additional geospatial datasets from other public servers and authorized sources may be integrated. Each new dataset will be subject to the terms and licenses of its original data provider.
Users are advised to consult the original data providers directly for the most current data and for any critical decision-making related to disaster risk reduction, land use planning, or emergency management.
The Application enables users to export selected administrative boundary geometries in the following open geospatial file formats, all generated entirely within the user's browser:

This Application is built on the principle that geospatial data about the Philippines should be freely accessible to every Filipino and to anyone with a legitimate interest in understanding the country's geography. All data available through this Application is open-source, compiled from public servers and authorized sources. The developer is committed to keeping this Application free of charge, free of advertising, and free of any barriers to access.
By centralizing and simplifying access to diverse geospatial datasets in interoperable open formats (GeoJSON, Shapefile, GeoPackage), the Application aims to reduce the technical barriers that often prevent communities, local government units, researchers, journalists, and civil society organizations from engaging with geographic information relevant to their work and lives. Any selling or commercialization of downloaded files is strictly prohibited by the original data owners and authorities.
The developer reserves the right, at their sole discretion, to modify, suspend, or discontinue any part of the Application at any time without prior notice. The developer also reserves the right to revise these Terms at any time. Revisions will be effective immediately upon posting of the updated Terms.
