I got lucky once that a had a site with an existing barn on it and also in the surveyor’s plan that I could use as a reference for Match Photo, but a totally empty site except for vegetation has nothing for Match Photo to latch on to. I put another reply in another thread, but it helps to know that when working with Field of View and Angle of view that SU has a bug when figuring Focal Length. I found it frustrating till I finally figured out what it was. The bug doesn’t happen when using TomTom’s Safe Frame plugin, so that may also help.
