In early June 2026, the Open Geospatial Consortium (OGC) officially released the OGC Features and Geometries JSON standard, commonly known as JSON-FG, as document number 21-045r1, version 1.0.0. After a quick review of the OGC standard details, the gist is that it addresses some capability gaps in GeoJSON, further expands GeoJSON's application scenarios, unifies specifications, and reduces private attributes. If you work with WebGIS, OGC APIs, or vector data exchange tools, you can follow along to understand what JSON-FG adds and assess whether your existing projects need to support it.
