Quick question...where did you get your DEM for the Moon, and
what format is it in? I recognize the software you're using
as I have it myself.

Brian,

It's a freeware version of Globalmapper licensed through the USGS. The
details a

On 18 January, 2007, the U.S.G.S. internet distributed the ULCN 2005
topographic DEM (Archinal et al 2006c). The ULCN 2005 DEM can be
displayed using USGS using private vendor software licensed by the USGS
for free public redistribution (Archinal et et al 2006c, USGS 2006f).
The freeware also allows to user to register images to the DEM, to
overlay DEM contours onto a user image, and to graph line-of-sight
elevation profiles.

The DEM has really low resolution. You won't be seeing 5km craters
leaping out like in the USGS Map-A-Planet relief map. But it useful for
these types of questions about long distance (plus 100km) grades.

I don't recall the specific format that is in the LPOLY.zip file, but it
was native to Globalmapper and I didn't have any problems loading it up.

See my article on crater depths in the GLRG's Issue #5 of Selenology
Today (Mar. 2007) for more background details.
