Lunar Surface with Bootprint

It's highly unlikely that Buzz Aldrin was thinking about photogrammetry when he stood on the Moon on July 20th, 1969. But by snapping two photos of his own bootprint from slightly different camera positions, he inadvertently made the first extraterrestrial photogrammetry capture. This model isn't the first to be created from these photos. There are several out there that focus solely on the bootprint. Most are heavily retouched and sculpted to make a visually appealing print. I decided to aim for accuracy and authenticity instead. This model reproduces all of the lunar surface captured in the photos, including the bootprint. Starting with high-resolution tifs from NASA, I created the model using Agisoft PhotoScan. The only processing I did beyond that was to make the scan printable. It consisted of filling holes and solidifying the model. You will notice the fill in the heel of the boot print and the far side of the small rock, which were in deep shadow and therefore provided no data. The model is designed to print vertically so it will reproduce the most detail possible. Now Scan the World can expand to the Moon!
