You can see how to go about making things like this in the tutorials on my Cartography Links page, accessible from the menu bar at the top of this page. (I watched them all and then took the bits I liked best.)
But today I thought it would be fun to gather them all up together here in one place. At the same time, I've put together another video tour showcasing all of these images.
|The Mighty Soltan|
I had a lot of fun making this image. I actually created a full equirectangular projection map of Soltan's "surface". I'm not sure it will ever be needed aside from in making this image, but you never know with fantasy settings.
Soltan is utterly vast: 110 times the size of its largest orbiting planet, Calidar. It's really very similar to our sun in most respects.
