Format description

GeoJSON is an open-standard format designed for representing simple geographical features, along with their non-spatial attributes. The format is based on JavaScript Object Notation (JSON).

The features include the following:

Points (addresses and locations)
Line strings (streets, highways and boundaries)
Polygons (countries, provinces, tracts of land)
Multi-part collections of the preceding three types

GeoJSON uses a geographic coordinate reference system, World Geodetic System 1984, and units of decimal degrees.

The GeoJSON format differs from other GIS standards in that it was written and is maintained not by a formal standards organization, but by an Internet working group of developers.

The GeoJSON format working group and discussion were begun in March 2007 and the format specification was finalized in June 2008. In April 2015, the Internet Engineering Task Force founded the Geographic JSON working group, which released GeoJSON as RFC 7946 in August 2016.
