This animation of a virtual flight over of the southwestern part of the Candor Chasma on Mars was made from HiRISE Digital Terrain Models (DTM’s).  Essentially DTM’s are made from two images of the same area on the ground taken from different angles, a stereo pair. The process of going from a stereo pair to a DTM is the hard part. Happily we have people who are up to the challenge.

The great thing about the DTM is the high resolution of the source imagery, the HiRISE images coming from the Mars Reconnaissance Orbiter are normally between 0.25 and 0.5 m/pixel.  The derived terrain is about four times the source, so we are talking a vertical precision in the tens of centimeters. ¹
