Web GIS Demo — Interactive Map of Benin
An interactive web mapping app: departments and communes of Benin, clickable layers and spatial radius analysis — built with Leaflet, React-Leaflet and Turf.js.
Interactive Map of Benin
Switch layers, hover features, then click anywhere on the map to run a spatial radius analysis.
Administrative boundaries: geoBoundaries (gbOpen). Localities: illustrative data. Projection EPSG:4326 (WGS84).
GIS skills demonstrated
Web cartography
Rendering GeoJSON vector layers (departments, communes, points) with Leaflet: symbology, popups, tooltips and hover interactions.
Spatial analysis
Client-side proximity query with Turf.js: geodesic distance, radius filtering and population aggregation over georeferenced data.
Geospatial data
Handling standard formats (GeoJSON), coordinate systems (EPSG:4326) and official administrative boundaries, ready for PostGIS.
