11.17.5. 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, such as mysql.

  • Application programs written in any language that supports a MySQL client API
