geoJSON
GeoJSON is an open standard for representing geographic information in a JSON file. It is commonly used for sharing data between web services or manipulating vector data in the browser. A GeoJSON file consists of either a FeatureCollection or a single object. GeoJSON defines six basic types of geometry: Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon. A geometry can be combined with attributes known as properties to define a Feature.
