GeoJSON

GeoJSON is an open-standard geospatial data format based on JavaScript Object Notation (JSON), commonly used to store, transfer, and visualize geographic information. It supports spatial geometries such as Point, MultiPoint, LineString, MultiLineString, Polygon, and MultiPolygon, as well as collections of geographic features. GeoJSON can combine geometry with attribute data, allowing each spatial feature to carry descriptive information such as names, classifications, IDs, or other properties. Its simple text-based structure makes it suitable for web mapping, GIS applications, spatial APIs, and location-based services. GeoJSON is widely supported by modern mapping frameworks and geospatial software, making it useful for publishing interactive maps and exchanging vector data between different systems. It is particularly effective for web-based workflows where lightweight, machine-readable geographic data needs to be transmitted efficiently and rendered dynamically.
