Titan: Ganymede with frequent small impacts
Once the composition of Titan's surface is established, then the radar images will be compensated for material properties.
If Cassinin survives, there will be multiple radar images - These will have to be combined to improve resolution.
Sorry, but at Titan's temperature "liquids" are likely to be "ices".
The interesting thing about Titan is how much the ridge systems have been degraded by impact - the most interesting thing is trying to identify the source for the small impactors.
What the colors do is highlight how many of these there are.
