Photogrammetric model of the Apollo 11 landing site based on the surface imagery
Description
This dataset contains a 3D model of the Apollo 11 landing site based on photogrammetric analysis of 122 (from 123) photographs taken by the crew during their only EVA (Magazine S), and 7 photographs taken from the windows of the Lunar Module. Coordinates of the camera stations and camera rotations are accurately determined, coordinates of multiple benchmarks fixed to hardware elements (the lunar module, flag, seismometer etc) and natural features (boulders, rocks) are found with high precision. The coordinate frame is approximately horizontal and is found from the positions of the Sun and Earth in surface photographs. For more details, see readme.docx file.

Steps to reproduce
Using digital photogrammetry software, create a 3D reconstruction of the Apollo 11 landing site. Photographs taken on the lunar surface by the crew are to be analyzed. Rocks and hardware elements may be used as benchmarks, reseau grid and blurring will help to determine linear sizes and focusing distances of individual scans. The local horizontal frame may be introduced by comparing the positions of the Earth and Sun in photographs with their actual coordinates in the lunar sky during the EVA. The position of the Sun may be found from analyzing shadows.
