I don't know which photography you have, but oftentimes that can be off significantly due to inaccuracy of the camera/gps, but also due to warping issues. You're really much better off getting multiple GPS points. You may even find your GPS wasn't as off as you thought. :) - Serge _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
