Ahhh....Probably Fractal Terrains. But with FT, you make the map (the world really), but you could then export to CC3 to make the maps themselves.

See the following link. I made a new Campaign World (roughly earth sized, similar tilt etc.) in Fractal Terrains, and then exported to CC3 to make the regional maps.
