ah... didn't even know about those maps.
anyway, I just finished to redraw the GC map with autocad (a vectorial program).
it can be useful as a tool for building startpos, plan things or whatever you want.
if you need it I can send you the file but it's an autocad file, not PS nor gimp.
here are the couple of things I've done with it till now
Tell me what you need and I can prepare a custom jpg, the file is made so to be highly editable depending on what you have to do.
Or you can just use the third one and do a "color selection" with PS/Gimp. I have a 3000 pixels version if you want it.
