Very high resolution Mars topography data

I see that the USGS now has some very high resolution elevation maps for some parts of Mars:

The good news:
It really is very fine resolution, good enough for ripples on the dunes from what I can see.

The bad news:
Downloads are HUGE, (over 1 Gb!)
I'm really struggling to find something that can make sense of the data, even the image maps, (which I would have expected to be straightforward).

Has anyone else managed to get at the data in a usable form, e.g more widely supported image format, DEM, terragen, vue etc?

Hi Nick,
If you are interested in Mars topography maps (DEMS), I suggest using Vista pro4 it is a software program that will allow you to fly over the surface of Mars....really. They offer the Mars CD as an xtra to the main program. They also have a converter for other type of files and well and you can make your own dems....., have a look at it and see what you think. I have used it for many years....and love it. I hope this will help. Let me know...
