# GeoJSON Source: [https://geojson.org/](https://geojson.org/) GeoJSON is a format for encoding a variety of geographic data structures\. ``` { "type": "Feature", "geometry": { "type": "Point", "coordinates": [125.6, 10.1] }, "properties": { "name": "Dinagat Islands" } } ``` GeoJSON supports the following geometry types:`Point`,`LineString`,`Polygon`,`MultiPoint`,`MultiLineString`, and`MultiPolygon`\. Geometric objects with additional properties are`Feature`objects\. Sets of features are contained by`FeatureCollection`objects\. ## [The GeoJSON Specification \(RFC 7946\)](https://tools.ietf.org/html/rfc7946) In 2015, the Internet Engineering Task Force \(IETF\), in conjunction with the original specification authors, formed a[GeoJSON WG](https://datatracker.ietf.org/wg/geojson/charter/)to standardize GeoJSON\.[RFC 7946](https://tools.ietf.org/html/rfc7946)was published in August 2016 and is the new standard specification of the GeoJSON format, replacing the 2008 GeoJSON specification\.
