MySQL Reference Manual for version 4.0.18.
17.5 Analyzing Spatial Information
After populating spatial columns with values, you are ready to
query and analyze them. MySQL provides a set of functions to
perform various operations on spatial data. These functions can be
grouped into four major categories according to the type of operation
they perform:
-
Functions that convert geometries between various formats
-
Functions that provide access to qualitative or quantitative properties of a geometry
-
Functions that describe relations between two geometries
-
Functions that create new geometries from existing ones
Spatial analysis functions can be used in many contexts, such as:
-
Any interactive SQL program, like
mysql or MySQLCC
-
Application programs written in any language that supports a MySQL client API
