+Geospatial Types
+----------------
+
+The ``geometry``, ``point``, ``linestring``, and ``polygon`` types are also known
+as the "geospatial types". CakePHP offers limited support for geospatial
+columns. Currently they can be defined in migrations, read in schema reflection,
+and have values set as text.
