Orthoprocessing of old scanned aerial photos without additional data

[ThomasSpehs]

I have 60 years old, scanned aerial photos, without any further information (no focal length, no fiducials, etc.); what I have are GCPs and elevations. Is there any way to use the Pro Orthomapping workflow for processing? I got stuck when asked for the above parameters but can’t provide them.

Hi Thomas,
my colleague Cody has compiled a lot of useful information on historical imagery in this pdf and then in this workflow. Given the limited amount of metadata you have, might not be applicable - but a good read anyway. You might end up to manually pin-point your gcp's ...

Please wait a day or two - I will get back to you as soon as I can.

I appreciate the response from Guenter, and those materials he referenced were our best workflows from a few years ago, but Ortho Mapping in Pro has improved much more as of version 2.6.

When you say "no fiducials" do you mean that you have digital files but the fiducials are not visible?

And can you tell me how many photos you have to process?
