According to google, quite a bit, but I'm not really familiar enough with it to comment. Generalising it should be easy enough, the only trick is that the RDF engine needs to spot the polygon/whatever pattern at import time and index it using a normal GIS engine. Triggers would help there, but SPARQL is not quite that sophisticated yet. - Steve
