About GeoJSON

GeoJSON is an open standard format for encoding geographic data structures using JSON. It supports points, lines, polygons, and multi-part geometries along with feature properties.

Extensions: .geojson, .json
Software: QGIS, Mapbox, Leaflet, OpenLayers, PostGIS, ArcGIS
Limitations: Limited to WGS 84 (EPSG:4326) coordinate system. No built-in styling. Large files can be slow to parse.

Extensions: .kmz
Software: Google Earth, Google Maps, QGIS, ArcGIS
Limitations: Same as KML (WGS 84 only). Requires extraction to edit the underlying KML.
