Anyone have the technical info on how this was done and put together? Looking at other pages, it appears this was created by Villanova University in Pennsylvania (http://www1.villanova.edu/main.html) for the Vatican, and they appear to have several folks actively publishing in photogrammetry journals. It looks like it was done with some very high quality photogrammetry (http://en.wikipedia.org/wiki/Photogrammetry), and I'd be interested to see what program they used, and if its available, as my agency could probably find some uses for it.
