A couple of days ago I posted on Universe Today some new Mars flyover videos created by Doug Ellison from UnmannedSpaceflight.com. He now has rendered a few more, and this one is my favorite: Bahram Vallis. Hang on to your hat when you approach the cliffs! Doug is able to create these amazing 3-D flyover videos from data from the HiRISE camera on the Mars Reconnaissance Orbiter. Using DEM (Digital Elevation Model)– (also known as DTM Digital Terrain Model) files provided by the HiRISE team. Since he is using actual high-resolution data from HiRISE, Doug says the terrain seen in the movies has accurate vertical scaling and is not exaggerated. You can see more on Doug’s You Tube channel, or see my post on Universe Today.
