The goal of Geo::OGC::Geometry is to implement the Open Geospatial Consortium, Inc.® (OGC) simple features API. 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. this Manual, Integer Types (Exact Value) - INTEGER, INT, SMALLINT, TINYINT, A.
