Good programs for map drawing

[Shadowstar]

I was looking around the forum for posts about programs people use to draw maps for Dom3, but couldn't really find much. I've experimented with Autorealm but it tends to get pretty difficult to use when working with high resolution maps. I'm thinking, we can use this thread to just list our favorite map drawing programs, so other people like me looking for a good way to make maps might not have to do so much searching.

Autorealm can be found here: http://www.autorealm.org/
