Hi,<br>
Petra Holden, a brilliant young UCT PhD candidate, gave a talk on
this at GISSA WC in June.<br>
Her topic was: A semi-automatic aerial triangulation approach to
the orthorectification of warped historical aerial images covering
mountainous terrain.<br>
<br>
I'm sure you can track her down if you want to.<br>
Regards,<br>
Zoltan<br>

Have you considered SfM (structure from motion) for the historical
imagery? <br>
