How to make a topographical / contour map?
 

In another game, someone is able to great a combat map from the heightmap of the game. Check out the first post for pictures, but the link to the first reply explains the process:

Perhaps because of the way the maps are integrated in the game, I can only get a minimap.dds from a mod for Baskerville or some "map" or "map.grs" and such.

Is there a way I can export a heightmap file I can actually view in Windows with L3DT or some contour making program of heightmaps?
