I'm looking for a recent map ot Titan. Steve Albers's page links to one done by Fridger Schrempp in April 2005. Cassini has done a dozen flybys since then. Does anyone know if an updated map has been released.

Recently I have tried to put together an informed but decidedly artistic depiction of the topography of Mayda Insula.
I have used as a basis the relatively low resolution DEM derived from Cassini RADAR stereogrammetry from Kirk et al. 2008. This has been modified to trace apparent dissection of the terrain visible in the T25 and T28 RADAR swaths, as well as the beautifully processed version made available here by Ian. Finally this has been loosely verified by iteratively illuminating the resulting DEM and comparing it with the radar image to try to by-eye match highlights and shadows resulting from the topography. Finally I have convolved the DEM with a gaussian kernel to ensure it is still largely in agreement with the original Kirk et al. elevation model. All in all it is far from perfect, but it was an interesting exercise and hopefully you will enjoy the result. I include a top-down view of the DEM, an animated gif comparing my illuminated DEM and the RADAR image, and an oblique perspective view of the island (or peninsula, seems hard to find anyone certain about this) with exaggerated elevation. |
