Hi Kirk and Charles, Thanks for your reply. This is what we know… CAMERA: Wild RC8 and RC10 152mm Focal Length. ALTITUDE: 4,560m with Block Adjustments for Mountainous areas IMAGE OVERLAP: 60% along track 25% side lap and all flight line Orientations East – West except for offshore.
Im afraid though that GPS just wasn’t a thing when these images where captured. We have been looking at reverse geotagging the Images, that is we know there location…ish and we can convert them to jpegs with EXIF values assigned in theory. Though the biggest issue is, in talking on the guys on the Open Drone Mapper forum, our overlaps aren’t sufficient for SFM, so an automated process will be out of the question. Once again, thanks for getting back, if you can think of anything else, please let me know.

If the images have a high endlap and sidelap, you could use commercial software such as Pix4D or Global Mapper to orthorectify the images based on structure from motion. Check into drone orthorectification software.

Any Ideas, help, guidance welcome. I have thought about maybe even reverse engineering the Flight Plan, then using OpenDroneMap to georeference the Images.
