This web-based mapping application is designed to enable United Nations staff and users from African member states to instantly visualize and map their own data directly in a web browser, fully aligned with United Nations standardized mapping practices. # UNECA Rapid Mapping Browser-based rapid mapping tool for loading, styling, filtering, and exporting geospatial data. ## Features - Load data from local files (`.geojson`, `.zip`, `.csv`) - Import datasets from public HTTPS URLs (`.geojson`, `.json`, `.csv`) - Attribute-based thematic styling and class table editing - Continent/country filtering - Export outputs as PNG, PDF, and SVG ## Run No build step is required. 1. Open `index.html` in a browser, or 2. Serve the folder with any static server. ## Data Limits - Local upload size: `1 GB` per file - Remote URL import size: `512 MB` - Remote import timeout: `300 seconds` - Maximum features per dataset: `1,000,000` - Maximum vertices per dataset: `10,000,000` ## Browser Compatibility - Recommended: latest stable versions of Microsoft Edge, Google Chrome, and Mozilla Firefox. - Supported: Safari 16+ on macOS. - Not supported: Internet Explorer and legacy, non-evergreen browsers. - For best performance with large datasets, use a desktop browser with hardware acceleration enabled. ### Tested Export Matrix Test baseline date: 2026-03-11 (latest stable browser channels). | Browser | Rendering | PNG Export | PDF Export | SVG Export | Notes | |---|---|---|---|---|---| | Microsoft Edge (latest) | Supported | Supported | Supported | Supported | Recommended for large map exports. | | Google Chrome (latest) | Supported | Supported | Supported | Supported | Recommended for large map exports. | | Mozilla Firefox (latest) | Supported | Supported | Supported | Supported | Supported with good stability in normal dataset sizes. | | Safari 16+ | Supported | Supported | Supported | Supported | Works, but can be more sensitive to cross-origin canvas constraints. | Export reliability depends on data size and CORS: - If remote tiles or images do not allow CORS, raster exports (PNG/PDF) can fail or be incomplete. - SVG export is generally most resilient for vector-heavy outputs. - Very large layers can exceed browser memory limit …
