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.
