This will result in a very rough estimate. Estimating height from displacement is only possible if you have stereo-photo's with at least 60% overlap or when you know every photograhic detail like focal length, photo-centerpoint and so on. You cannot accuratly estimate height from displacement in constructed mosaics. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
