Hi all,
1. Very old aerialphotographs for which you do not have supporting data like
focal lengths etc, except a stereo pair of photos, how to convert them to
digital ??
2. Can a normal (Hp) A4 scanner work for this.
3. Any one on GRASS list tried it this way.

It won't explode :-) I mean that even if you are off from the true value it
may still get out a result.
