Cartography Help

I’m sure some of the people here have played Warcraft III, or World Of Warcraft, and I was wondering if anyone knew anywhere I could look to get some tips on creating maps like they use. In Warcraft III they were the maps that were shown during the loading screens:

and in World of Warcraft the World Maps are all nicely made, and detailed. I’m planning on working on a project where that sort of map would be perfect, but I don’t know where to even start to learn how to make them - or something similar.
Any help would be great! :slight_smile:
