If geocontrol isn't used much on these forums, then I probably should do atleast somekind of tutorial about the program. Geocontrol was probably the shortest stage on the final version of this map, so it shouldn't be too much of trouble. As Redrobes remembered, the application does support fluvial flows, but to be honest, I took a shortcut on this map and didn't bother using them But you can expect a tutorial to follow in the next 14 hours.
