 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 MySQL Query Browser
 
    * Application programs written in any language that supports a MySQL
      client API
