MySQL has data types that correspond to OpenGIS classes. Some of these types hold single geometry values:
GEOMETRY
POINT
LINESTRING
POLYGON
GEOMETRY
can store geometry values of any type. The other single-value types (POINT
, LINESTRING
, and POLYGON
) restrict their values to a particular geometry type.
The other data types hold collections of values:
MULTIPOINT
MULTILINESTRING
MULTIPOLYGON
GEOMETRYCOLLECTION
GEOMETRYCOLLECTION
can store a collection of objects of any type. The other
collection types (MULTIPOINT
, MULTILINESTRING
, MULTIPOLYGON
, and GEOMETRYCOLLECTION
) restrict
collection members to those having a particular geometry type.
