Map to Globe, a website that can help make your game world come to life. I haven't done much "under the hood".....yet, but there are a lot of cool options to make your maps come to life.
Things like adding height maps, switching out map projections, or even just randomly create a globe.
I spent a few minutes quickly coloring one of my old maps (the intro graphic) just to see it in action and I was pretty impressed. Definitely worth checking out Map to Globe.
