Hi folks, I'm evaluating features of different spatial databases as part of my bachelor thesis. My comparison includes PostGIS, DB2 spatial extender and MS SQL-Server.
I'm looking for an overview listing those PostGIS functions using the spatial index. The other DBMS documentations state exactly which functions do use an index, which I miss in the PostGIS documentation. Is it right to say that - from the set of OGC topology/measurement functions - the following are using the index? Equals, Intersects, Touches, Crosses, Within, Contains, Overlaps And not: Distance, Disjoint, Relate? (This in fact is stated in the docs [1]). Thanks!
