Hi. Nice maps you've got here!

I am running a D20 campaign and my players are strongly interested in building up their own domains, and my little Moleskine maps are not detailed or electronic enough to build towns on.

One player used AutoRealm to build a necromancer's stronghold. The other is more ambitious and has begun building a town in Google SketchUp. I am proud of them both and have asked them to register on this site.

The aforementioned town is in a hilly area near a river, and we need realistic terrain upon which to put it. It needs to be miles in scale and meters in precision, and should map the riverbed. I am hoping to find the right kind of software for this by looking around this (dauntingly large) site.
