Understanding GeoJSON

JSON-Based Format

GeoJSON is a format for encoding geographic data structures based on JSON (JavaScript Object Notation). It defines several types of JSON objects:

  • FeatureCollection — A collection of features
  • Feature — Contains a geometry and properties
  • Geometry — Points, LineStrings, Polygons, and their Multi variants

Unlike other GIS formats, GeoJSON is designed to be both human-readable and machine-processable, making it ideal for web applications.
