However, I have no idea how to go about making these maps. However, many years ago I used to play Simu Trans (http://www.simutrans.com/en) a lot ... a great deal in fact. For me (as a non-coder) the best implementation that Hajo ever made was to allow the import of grey scale images that created the maps. The level of grey, from black to white, determined the height/elevation of the terrain. This gave a base map that could then be populated with trees and stuff. I particularly liked this approach because it meant I could make maps I liked from scanned images (playing the Faero Islands was a strange habit I had back then) I know that Simu Trans has moved on a lot over the years, and I don't really play it any more, but you should be able to get plenty of ideas for this concept from his code.

After all, this is where the juicy maps are generated from, right? Here you are: http://pastebin.com/UJ9pT5LN Basically it is diamond-square algorithm.... Top Quote

But I like the idea of taking real-world heightmap and converting it into wideland map... In fact it is very close to what I am doing now... BTW, I used to play simutrans as well few years ago...
