Well, since I've been stalled by reality (gonna have to find a new home soon, and attending school, and working...) and not being able to contribute much, especially not a mod to show off these utils in,
check out these map making utilities. Both are freeware:
Dungeon maps - dungeon crafter ( Dungeoncraft - drungeoncrafter... small world, eh?)
http://www.dungeoncrafter3.com/
Dungeon crafter util is my favorite becuz it exports BMP maps and allows you to make a graph paper-style overland map. You have to resize the map by 75% due to the square size being 20 (DC uses 16). BUT, you can use custom art by loading your own bmp images into the util (I believe Uatu made an overland map template that could be used with this program). It doesn't just do dungeon maps, either; as I wanted to do a top down style for my smaller towns (instead of the "smalltown" event")
Another one of note is you can google "campaign cartographer" and "autorealm" and find the older versions of these for free download as well
check out the worldgen fractal mapper:
