Heightmap Generator for a City Generator

Gold, my friend, absolute gold! I wish I'd come here first instead of trying to come up with my own crummy system by myself with virtually no knowledge of erosive processes. Right, I'm off to rework the whole thing...and probably read a few geology books or something.

So, hopefully these are a bit better, and not worse, than the last lot. It calculates the cutting power using the slope now instead of a bunch of successive botches. It still uses successive botches for other stuff though, most notably the getting rid of the sinks bit. So it fills the sinks, adds some perlin noise to the sinks, and does this about thirty times. If the map has big enough sinks, the cutting power is very low and the maps don't look very nice. Obviously this is nothing like what really happens. I guess the sinks would really be filled in with sediment and allow the river to continue flowing or something like that.

And, basically all the towns are surrounded by mountains, which isn't very realistic either but hey, I like mountains.

Anyway, if anyone's still reading this thread (Mr. Wilbur, perhaps...), here's some more heightmaps...
