This would make a cool art installation. If you can get access to one of those giant screens that you see demo'd at E3. You can visualize the entire Land of Hyrule from Lengend of Zelda. With a tiny Link navigating his way through the world ;)

The lost woods might confuse the algorithm pretty good.

If you just want big maps, that's already been done (by hand):

In the 1980s, books like How to win at Nintendo Games were published with strategies, cheats, maps, and so forth. That particular line of books were cheap black-and-white (well, yellowish, IIRC) paperbacks. But there were full-color glossy strategy books that included full maps for games.

I had a bunch of those books. I didn't even have an NES! (Though I desperately wanted one...) But I was so enamored with video games that I pored over them.
