GeoJSON is the web-standard format for maps: points, lines and polygons with properties, consumed by every mapping library.
Typical use: Convert SHP/KML/GPX into GeoJSON to feed Leaflet, Mapbox or any web map.
About the GeoJSON format
GeoJSON is the map format the web agreed on: a FeatureCollection of points, lines and polygons, each carrying arbitrary properties, in plain JSON. Leaflet, Mapbox, D3, QGIS and PostGIS all consume it directly, which is why almost every GIS workflow ends with “export as GeoJSON”.
Converting the older formats into GeoJSON (SHP, KML, GPX) is the bridge from institutional and device data into anything a browser can draw.
