Forum:Map

How do you create those maps for fictional countries where there is a small part of map with a highlighted color that represents that land?

Like this: http://conworld.wikia.com/wiki/File:WessexMapMarked.png

And how do you make the larger ones with multiple color codes?

I want to make a wiki map out of them as well.
