What is GeoJSON?

GeoJSON is a format for encoding a variety of geographic data structures using JavaScript Object Notation (JSON). It supports geometry types like Point, LineString, Polygon, MultiPoint, MultiLineString, and MultiPolygon, as well as feature collections that combine geometries with properties.

Example GeoJSON Point:

{
  "type": "Feature",
  "properties": {
    "name": "Sample Location"
  },
  "geometry": {
    "type": "Point",
    "coordinates": [-74.006, 40.7128]
  }
}

Key Features

Interactive Drawing
