Topography / elevation data of Mars For a design project I'm looking for elevation data for Mars' surface - the idea is to replicate a surface area of Mars as a physical model, using the elevation data to create a very rough 3d model of that particular area's topography.

Where can I find such data?
Try this link http://geo.pds.nasa.gov/missions/mgs/megdr.html
This should have the data you're looking for, though you may need to process it a bit to get it into a format hat will be usable.
