A JSON-based open standard format for encoding geographic data structures including points, lines, and polygons.
GeoJSON is the standard format for geographic data on the web. It represents geographic features as JSON objects with a geometry (coordinates and shape type) and properties (attributes). GeoJSON uses [longitude, latitude] coordinate order.
GeoJSON is supported by web mapping libraries like Leaflet and Mapbox, GIS tools like QGIS, and most Canadian open data portals.
