MySQL provides functions to perform various operations on spatial data. These functions can be grouped into several major categories according to the type of operation they perform:
Functions that create geometries in various formats (WKT, WKB, internal)
Functions that convert geometries between formats
Functions that access qualitative or quantitative properties of a geometry
Functions that describe relations between two geometries
Functions that create new geometries from existing ones
For general background about MySQL support for using spatial data, see Section 11.5, “Spatial Data Types”.
