As I have said before in many threads, I don't like non-real maps for Colonization. I don't know why, but it drives me nuts. I liked the Westward Ho mod, so I decided to make a map. The mapscript included was okay, but the lack of Pacific Ocean took out the fun for me when I played as California or Oregon. I converted Iuvavus' map from Civ IV and added the new colonies. There are no resources, but with Colonization, they are not truly nessesary...
