Noob Map editing question

[Xietor]

Thanks for the help. I got the method down for editing, but the terrain does not change. And I tried the program suggested, but I do not have the Visual basic program yet.

Does anyone have a large (275 or so) province map already made? Basically I like the 3600 x 2000(oblong shape) with many choke points for easy defense. Typically i also have about 25 water squares, but try and avoid 1 big water area.

I am going to look into buying the VB program and try to make 1 myself.
