It took me 72 hours to add a GIST indexed geography column, but now I can report the results:
I don't see any noticable performance hit in going from goem x geom intersection to geog x geog intersection (where the geog column in the table is 20M in size). I think this is due to the fact that the search is disk speed limited. -- View this message in context: http://postgis.17.n6.nabble.com/Why-should-these-boxes-intersect-tp4998895p4999088.html Sent from the PostGIS - User mailing list archive at Nabble.com. _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
