GeoJSON is widely supported, including in most implementations of the OGC API &#8211; Features &#8211; Part 1: Core Standard. However, GeoJSON has intentional restrictions that prevent or limit its use in certain geospatial application contexts. For example, GeoJSON is restricted to using only WGS 84 coordinates in Longitude Latitude axis order, supports only the original Simple Features geometry types, and has no concept of classifying features according to their type.<\/p>\n<\/div>\n<div class=\"paragraph\">\n<p>The OGC Features and Geometries JSON (JSON-FG) Standard specifies GeoJSON extensions that provide standard ways to support these and other additional requirements.
