Or you could use this as a start and run it through Wilbur, which is a free heightmap generation and editing tool. It's a little difficult to use, but its creator, Joe Slayton aka Waldronate, is a member of this forum and is usually happy to help people use it. I'm not sure how it does with continent-scale erosion, though. I've only used it for maps less than 6400 square miles.
What is the USGS? I'm looking now.. and been playing around with this Wilbur program, it seems like all the commands are through filter and the top menu. Would I have to redraw this or could i import or what? thanks for reply
