This data type is internally represented as an Oracle object data type. As with GEOMETRY, we recommend that when you have very large polygons, but are doing queries in small areas, you "denormalize" your geometric data into smaller chunks so that the index can effectively subquery parts of the object and so queries don't have to pull out the whole object every time. Models comprising simple semantics along with structured geometry Such models are often created through data interpretation processes like photogrammetric object extraction or automated reconstruction of geometric primitives from laser scanner point clouds.
