Cassini RADAR altimetry
Last week at the Lunar and Planetary Sciences, the Cassini RADAR team presented results on Titan topography obtained using the altimetry mode on their instrument as well as through radar clinometry, or shape-from-shading. Below are links to the three altimetry profiles. The numbers are a bit hard to read on the altitude side of things, but each major tick mark is 100 meters of elevation. As you can see, the outbound profile from T3 shows that there is some topography on the surface of Titan. It should be pointed out that spacific features of these altimetry profiles have not been mapped to specific surface features as of yet, so they had no idea where that sharp, 200 meter "cliff" is. Notably, all three profiles have an downward, eastward trend to them, suggesting regional slopes.
