About What is GeoJSON?
GeoJSON is an open standard format designed for representing simple geographical features, along with their non-spatial attributes. It is based on the JSON format and is defined in RFC 7946. GeoJSON supports the following geometry types: Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and GeometryCollection.
Features in GeoJSON contain a geometry object and additional properties. A FeatureCollection contains a list of features. GeoJSON uses the WGS 84 coordinate reference system, with coordinates specified as longitude and latitude (in that order).
