The new map also shows a dry basin in Titan's southern hemisphere. There's a good chance this was once a sea, thousands of years ago when humans were still in the process of migrating out of Africa. The climate on Titan changes gradually over time so, while most of the hydrocarbon lakes and seas are currently in the northern hemisphere, the south used to be much wetter.

Interestingly, as well as seas, Titan also has deserts. Sand seas are seen all across this hazy moon. Some of these are trapped in basins, while others are spread across wide open plains, where they're shaped by Titan's winds as well as the contours of its landscape.
Unfortunately, this new map of Titan is only a topographic map, and not a complete map. A similar map of Earth would show mountain ranges and land masses, giving a good impression of our planet's surface, but with no details. With a topographic map of Earth, we wouldn't be able to pick out any fine details, and smaller landmasses like Japan, Madagascar, or New Zealand would be missed entirely.
