GeoJSON is a format for encoding a variety of geographic data structures. It is used by many web services and applications to store and exchange geographic data.

Key Features

  • GeoJSON Objects: Represented as a JSON object, with a required type property and optional properties object.
  • Geometry Types: Supported types include Point, LineString, Polygon, MultiPoint, MultiLineString, and MultiPolygon.
  • Coordinate Reference Systems (CRS): GeoJSON uses the Well-Known Text (WKT) format to describe coordinate reference systems.

Geometry Types

  • Point: Represents a single location on the surface of the Earth.
  • LineString: Represents a linear path on the surface of the Earth.
  • Polygon: Represents a closed, linear geometric figure consisting of three or more points.
  • MultiPoint: Represents multiple points.
  • MultiLineString: Represents multiple linear paths.
  • MultiPolygon: Represents multiple polygons.

Example

{
  "type": "Feature",
  "properties": {
    "name": "Example Polygon"
  },
  "geometry": {
    "type": "Polygon",
    "coordinates": [[[0,0], [0,1], [1,1], [1,0], [0,0]]]
  }
}
