I'm not sure that your geography professor is correct. I've seen what purports to be a German orthophoto map prepared during the first world war. It was on an online auction site, and I was the under-bidder, so I don't know where it is now. Fortunately I did keep a copy of the photograph and can send it, if you or your professor contact me.

A geography professor is hoping to nail down the first ever orthophotomap. She has done extensive research on the history of remote sensing and aerial photo interpretation, and estimates that the first true orthophotomap (with rectification) was probably made in the early 1950s. Is anyone out there in mapland the proud owner of this piece of history or at least know of it?
