Election Data

Comprehensive electoral data from the 2022 Philippine Presidential Elections, sourced from official COMELEC tabulations. This dataset includes precinct-level voting records, municipality and provincial aggregates, voter turnout statistics, and candidate performance metrics across all regions. The data has been meticulously cleaned and structured for geospatial analysis and visualization, enabling detailed examination of voting patterns, demographic correlations, and regional political trends. Available in multiple formats including CSV, JSON, and GeoJSON for seamless integration with mapping and data analysis tools.

Boundary Data

High-resolution administrative boundary data for the Philippines, encompassing all hierarchical levels from national down to barangay subdivisions. This GeoJSON dataset provides accurate geometric representations of regional, provincial, municipal, and city boundaries, complete with administrative metadata including region codes, province names, and population statistics. The boundaries are optimized for web mapping applications with appropriate simplification for efficient rendering while maintaining cartographic accuracy. These datasets enable precise spatial analysis, choropleth mapping, and territorial visualization of socio-economic and political data across the Philippine archipelago.

Flood Control Projects

Comprehensive database of flood control and mitigation infrastructure projects across the Philippines, sourced from government transparency initiatives and public works departments. This dataset catalogs flood control facilities including dikes, drainage systems, pump stations, retention basins, and river rehabilitation projects. Each entry includes project location coordinates, implementation status, budget allocation, contractor information, and completion timelines. The data supports analysis of flood risk mitigation efforts, infrastructure investment patterns, and disaster preparedness planning. Geographic coordinates enable precise mapping of flood control assets and identification of coverage gaps in vulnerable communities.

WebGIS Resources

Curated collection of open-source WebGIS technologies, libraries, and tools utilized in developing this interactive mapping platform. Built primarily on MapLibre GL JS, an open-source fork of Mapbox GL JS, the platform leverages modern vector tile rendering for smooth performance and dynamic styling. The tech stack includes essential geospatial libraries for coordinate transformations, spatial analysis functions, data processing utilities, and custom map controls. Additional resources encompass basemap providers, tile servers, geocoding services, and styling tools that enable rich cartographic visualization. This repository serves as a comprehensive reference for developers building web-based geographic information systems with emphasis on performance, interoperability, and user experience.
