Based on http://spatialreference.org/ref/epsg/32661/ the bounds for 32661 are -180.0 60.0 180.0 90.0 so I don't understand the values you're using. (That might not explain the spurious tiles you're seeing though) -- Eric _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users
