Hi list! I'm wondering if there is a formula to generate 20 tables (one for each zoom level) of square polygons, representing a tile grid of popular TMS like OSM or MapQuest?
I guess there shoud be a way to convert x,y,z tile coordinates to lat/lon coordinates in PostGIS. _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
