This is a tall order, but I thought it might be worth asking.
I'm working on a project where I need to basically fake a large urban map: streets, parks, rivers, etc. Essentially I'd like to wind up with something that looks like Google Maps at one or two stages short of maximum zoom.
I don't really want to spend an infinite number of hours drawing it, however.
Ideally, this would be something that I could generate in SVG, but reasonable resolution bitmaps would be fine too.
