WebIn MySQL, the SRID value is an integer associated with the geometry value. The maximum usable SRID value is 2 32 −1. If a larger value is given, only the lower 32 bits are used. All computations are done assuming SRID 0, regardless of the actual SRID value. SRID 0 represents an infinite flat Cartesian plane with no units assigned to its axes. WebMySQL supports geometry types of Point , LineString, Polygon , MultiPoint , MultiLineString , MultiPolygon, and GeometryCollection. Other geometry types are not supported. Only GeometryCollection can be empty. Such a value is stored with 0 elements. Polygon rings can be specified both clockwise and counterclockwise.
