How can I calibrate aerial photos or old maps? If someone has experience with his own aerial imagery or old (out of copyright) maps please share your experience. I looked on OSM wiki and there is really little, almost none information on how to do this. I'm about to get some aerial photos that a friend of mine who is a pilot will donate them to OSM. I looked on WIKI: http://wiki.openstreetmap.org/wiki/Out-of-copyright_maps#How_to_use_old_maps but there is says that there is a help section on gpsu.co.uk website that has instruction for calibrating bitmap images. I don't see it anywhere on that site :( Any help is much appreciated. Cheers, Valent. Have a look at this thread and see if its of any help http://lists.openstreetmap.org/pipermail/talk-gb/2009-September/004579.html David
