What is GeoJSON?

GeoJSON is a widely-adopted, human-readable format for encoding geographic data using JSON. It's the standard interchange format for web mapping and is supported by virtually all GIS tools and libraries. GeoJSON represents features with geometries (Point, LineString, Polygon, etc.) and associated properties.
