I was kicking around an idea I had with a fellow gamer today. Short version was to create a Google maps style fantasy world where you could zoom all the way out to see the full world and then all the way in to show any location at a 1sq = 5' DND scale. He said such a thing was impossible so I did the math and found that an average fantasy town would cover approx. 1 square mile, 5280'. Breaking it down you would need 441 50x50 square maps at this scale. Creating it a 1/5 this size still leaves you at about 84 50x50 maps. My question is has anyone seen a project on that scale before or is it really to crazed an idea to be viable?
