Gale Crater Topographical 3D Map
This is a 3D Topographical model of Gale Crater, where the Mars Science Laboratory Curiosity is roving around and blasting holes in the landscape.
It's 1:1925000 scale. The Curiosity Rover would be about two microns long, or about the length of one E. coli cell.
I wanted to be sure I was capturing the actual topography of the crater rather than some other optical property, and so I used the survey data from the Mars Orbiter Laser Altimeter (MOLA) Topography experiment aboard the Mars Global Surveyor. The data is available here :
