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, such as `mysql' or `MySQLCC'
* Application programs written in any language that supports a MySQL
client API
