Description
Overlaps, Touches, Within all imply spatial intersection. If any of the aforementioned returns true, then the geometries also spatially intersect. Disjoint implies false for spatial intersection.
This function automatically includes a bounding box comparison that makes use of any spatial indexes that are available on the geometries. |
Changed: 3.0.0 SFCGAL backend removed, GEOS backend supports TINs.
Availability: 2.0.0
This function supports 3d and will not drop the z-index.
This function supports Polyhedral surfaces.
This function supports Triangles and Triangulated Irregular Network Surfaces (TIN).
This method implements the SQL/MM specification.
SQL-MM IEC 13249-3: 5.1
