Linne Topography

Linné (2.2 km diameter) is a very young and beautifully preserved impact crater. LROC stereo images provide scientists with the third dimension - information critical for unraveling the physics involved in impact events. LROC NAC Digital Terrain Models (DTM) are made from geometric stereo pairs (two images of the same area on the ground, taken from different view angles under nearly the same illumination). LROC was not designed as a stereo system, but can obtain stereo pairs through images acquired from two orbits (with at least one off-nadir slew).
