Matrix Games Forums

I've found it suprisingly difficult to find maps that can be used in creating maps for this game. Mainly I'm referring to maps that allow you to easily identify waterways and elevation changes (but especially the waterways). I've even attempted to overlay waterway maps onto political maps but they don't always match up too well. If anyone's found a good map source I'd very much appreciate the tip. Thanks!
