Hi, Beowulf. I once used Dundjinni for some large-scale maps, and it is useable, but IMO not quite as readily-usable as say CC which is set up for that scale mapping. I recommend gettign GIMP (it's a free painting program--not specifically for maps at all), then follow a tutorial to make your large scale maps. There is a learning curve for GIMP--but this is true with every program, and GIMP will be very powerful once you have a few tricks up your sleeve. Oh, and you could also make very nice local/dungeon level maps in GIMP too--especially if you borrow items from our friends over at the Dundjinni forums, where you can find almost anything you could ever want to place on your map.

Otherwise, take a look at that link ravells posted.
