I wasn't sure where to put this but, assuming it hasn't been mentioned already, some of the image processing gurus here may be interested in a paper currently in press with Planetary and Space Science by Lohse et al. entitled "Derivation of planetary topography using multi-image shape-from-shading." I found what appears to be a 630 Kb PDF preprint from the XXth International Society for Photogrammetry and Remote Sensing Congress, which was held in Istanbul, Turkey, in 2004.

Online (and useful) planetary DEMs are frustratingly hard to find, except for the Earth, Mars and Venus, even though DEMs have also been generated for Mercury, the Moon, the satellites of Jupiter and Saturn, Miranda and probably more. For the Moon, the best bet is probably to wait for LRO.

In contrast, there is a lot of theoretical material online, the most interesting stuff in the context of planets/satellites probably being the work of Randolph L. Kirk.

This one is very interesting:

And possibly also this one although I haven't read it yet:

Searching on anything that starts with "shape from..." yields interesting reads. Shading, Stereo, Motion, Focus. try searching for "shape from X"

Shree k Nayar has a few really interesting papers on creating depth information from atmospheric scattering...
