Recent article in Science by Zebker et al.:
Zebker et al. Science in press, "Size and Shape of Saturn's Moon Titan". doi: 10.1126/science.1168905 (published online April 2, 2009) Link to abstract (pay-for article): http://www.sciencemag.org/cgi/content/abstract/1168905 Article on spaceref discusses this paper: http://www.spaceref.com/news/viewpr.html?pid=27912 Figure 3 from the Science article is a global elevation map relative to barycenter. Key points of article:
"Xanadu seems to be systematically lower than other parts of the equatorial belt, and not uplifted like most mountainous areas on Earth."

Right! Got my position wrong, but the arguments about the morphology being different from the features closer to the probe still remain - no lobes open in the upstream direction or downstream points. Does that feature show up on the radar? Need to look at that again. In this directon the Huygens DISR was looking into the light so genuine bits of highland terrain there would appear different to the Huygens island (which also has internal hollows with outward drainage to the plains like this feature). Roll on that VIMS paper.
