I wanted to see if it would be easy to create a "pure" elevation model starting with an already-created brightness overlay on an elevation model.
I tried it with a Venus global image at 180 degrees, using PIA00159 as the combined brightness/elevation model and trying to remove the RADAR-brightness part which I got from PIA00104 (after converting to black and white to match PIA00478). It ain't perfect, but it is a start. Here is the flow: Resultant full-res Venus derived colorized DEM is here: http://www.flickr.com/photos/31678681@N07/4618186455/ -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

Thanks, y'all. My original intent was making a decolorized version of the RADAR-brightness PIA00104 for an outreach presentation. But then, I got sidetracked into wondering the RADAR-brightness only image could be used to convert into a colorized DEM.
I don't have an exact application in mind yet, although it might be kinda fun to try and convert something like PIA11831 (Hotei Arcus) or PIA11829 (Belet-Senkyo region) into a pure DEM. -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
