  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.
