Aero-Data Corporation is a remote sensing consulting firm that offers high quality current and historical aerial photographs, custom aerial photomissions, photointerpretation, mapping, and expert witness testimony.
They also turn some of their pictures into 3-D pictures, and they have some samples on their site. One of the sample images is of Niagara Falls. Unfortunately I don’t have a pair of 3-D glasses around, but if you do, you should definitely check it out.
