[UW-GIS-L] topo profile of Mars?

[Liz Safran]

Hi, all,

Does anyone know how I can take advantage of the fabulous Martian 
terrain data in the newest version of Google Earth and also in Google 
Mars (which is similar to Google Maps for Earth) to create elevation 
profiles of Martian features?  None of the nice tools that I know about 
for doing this with terrestrial topography (e.g., 
http://freegeographytools.com/2007/elevation-profile-in-google-maps, 
or  http://www.gpsvisualizer.com/ ) seem capable of using a different 
baseline elevation data set.

Thanks in advance for any help you can provide.
