The funny thing about fantasy(and, for this purpose, I include science fiction in this category) cartography, is that you have to know more about the world to pull it off. In the real world the economics and geomorphology kinda... work themselves out. You just map out what is there*. To make a really good map of an imaginary world you really have to build that world.

Fortunately worldbuilding is my major interest, with cartography just 'cause... you know... who else is going to map my world.

Thanks for this resource. I will be checking this out in some depth.

*In theory, anyway. In practice, it can be a real chore to figure out where things actually are sometimes.
