Three-dimensional Data Types
3D data types exist in a three-dimensional coordinate space. The third coordinate can be either:
• An elevation and the data type will end in Z, or
• A measurement and the data type will end in M
The Z and M values are not considered in geometric calculations or in the generation of new geometry values, except when an M value is used with an LRS function.
3D types include:
• PointZ
• PointM
• LinestringZ
• LinestringM
• PolygonZ
• PolygonM
• MultiLinestringZ
• MultiLinestringM
• MultiPolygonZ
• MultiPolygoM
• GeometryCollectionZ

• PolyhedralSurfaceZ
• PolyhedralSurfaceM
• MultiCurveZ
• MultiCurveM
• MultiSurfaceZ
• MultiSurfaceM
• CircularStringZ
• CircularStringM
• CompoundCurveZ
• CompoundCurveM
• CurvePolygonZ
• CurvePolygonM
• TINZ
