GeoJSON
GeoJSON is an open standard format designed for representing simple geographical features, along with their non-spatial attributes, using JSON. It supports various geometry types such as points, lines, polygons, and multi-part collections, making it widely used for encoding geographic data structures. The format is human-readable and machine-parseable, facilitating easy integration with web applications and GIS tools.
Developers should learn GeoJSON when working on projects involving mapping, geospatial analysis, or location-based services, as it provides a lightweight and interoperable way to exchange geographic data. It is particularly useful in web development for rendering maps with libraries like Leaflet or Mapbox, and in APIs for serving spatial data due to its compatibility with JSON-based systems. Use cases include visualizing geographic datasets, building interactive maps, and integrating with geospatial databases.
