Geography functions

Geography functions aren’t compatible with all data platform connections. To check if your connection supports these functions, see Supported data platforms and feature compatibility.

Geography functions enable you to work with the geography data type to analyze locations, routes, and other geospatial data. For example, you can use geography functions to transform data into compatible formats for geography maps.
