GeoJSON是一种用于编码各种地理数据结构的格式，支持点、线、面等多种几何类型。GeoJSON对象可以包含附加属性，并且一组特征由FeatureCollection对象包含。2016年的RFC 7946成为GeoJSON的新标准规范。

GeoJSON

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)
In 2015, the Internet Engineering Task Force (IETF), in conjunction with the original specification authors, formed a GeoJSON WG to standardize GeoJSON. RFC 7946 was published in August 2016 and is the new standard specification of the GeoJSON format, replacing the 2008 GeoJSON specification.
