Here is a recent version of the global topographic map of Enceladus I have been working on.
These data were first shown at the March 2008 LPSc, and I am working on updates.
It is in simple cylindrical, so the poles are stretched way out at top and bottom, but the depression
at the south pole is visible along the bottom. also visible are several quasicircular depressions (dark in this rendering)
in equatorial and temperate areas. These are 1 to 1.5 km deep! I cant say more until the paper
we have submitted has been reviewed but will do so then. (The data do not include images acquired
last autumn, sadly, but will soon enough)!

Thanks for posting this - this is probably the most interesting Cassini-derived DEM I've seen so far. The terrain near ~(370,320) looks a bit weird and almost like a photo and not a DEM. I assume the very dark stuff there must be gaps due to low solar elevation?

this is strictly topography with no shading or other information. High is white, low is dark. there are areas of better quality of course, and i do have a few stray bits i havent added yet. it is and will be in progress until after last data returned!

i also have some high res data, which i have shown previously on Photojournal.

well the Abstract answers a question i had
was it derived from stereo images or more like my " pseudo topo" maps

it's nice and comparing a real one to what i draw , my "created ones "look a lot like the real thing .
I guess i must be drawing them right
