I am looking for a general reference that addresses quality control of orthorectification. We are currently orthorectifying many historical aerial photos that lack a detailed camera calibration report (we only know the focal length). We are getting reasonable-looking results, but will still like to find some guidelines on the process. Two immediate issues we have: 1) we have ca. 20% overlap using every 2nd photo in the flight line--is it imperative to orthorectify every photo? Seems like a lot of 'wasted' work due to high overlap. 2) we are not sure how to determine boundaries for patching adjacent overlapping photos.
Thanks,
Dan
