Mini Map

I want to have a mini map in my motorcycle game similar to World of Warcraft. My idea was to make a bunch of textures that were just renderings of my world from a top view. This would allow the user to see roads, buildings, lakes, exactly as they should be, and it would require very little effort to actually program the texture generator.

If I get my program to fly above the map and render a frame pointing down, how do I export that to a texture?

Does this sound like a good or bad idea? I think it will look great if done correctly and it doesn't seam like it will be that hard.

Thanks in advance!

That would be easier to do in real time, maybe once every few seconds. Thanks for the idea!
