17.4.1 MySQL Spatial Datatypes

MySQL has datatypes that correspond to OpenGIS classes. Some of these types hold single geometry values:

GEOMETRY can store geometry values of any type. The other single-value types, POINT and LINESTRING and POLYGON, restrict their values to a particular geometry type.

The other datatypes hold collections of values:

GEOMETRYCOLLECTION can store a collection of objects of any type. The other collection types, MULTIPOINT and MULTILINESTRING and MULTIPOLYGON and GEOMETRYCOLLECTION, restrict collection members to those having a particular geometry type.
