Since, as you know, I’m deeply interested in the mapping of the other planets and moons of the solar system, I was very much interested in two recent posts by Peter Minton, in which he takes Cassini imagery of Saturn’s moon Titan and generates maps from that imagery: here and here. There’s also a Flickr photoset; the image of the Titan island group here is his. Via Planet Geospatial.

Most extraterretrial “mapping” is simply orthorectified space-probe imagery imposed on a cartographic projection; it’s interesting to see an actual map of another world.
