Has anyone created DEM datasets for the MER (or any other) landing sites? I tried searching the site for 'DEM' but the darn search engine doesn't cope well with three-letter acronyms!

Ideally, I'd like to be able to use VistaPro or Vue d'Espirit to try to create some flyarounds - perhaps a low-level retracing of the rover paths. My copy of VistaPro, BTW, came with a whole series of DEM files for Mars (albeit at a large scale) and they have proved to be great fun.
