I build fictional worlds as a hobby, and sometimes I need to make a map of a globe and find myself in need of a program that can draw vector shapes onto a globe and project it onto a 2D map afterwards. The simplest way I've found to do that which fits my workflow is a program called GPlates. A program that simulates plate tectonics. I've never touched the simulation part, although it might be useful in my worldbuilding at some point. All I use it for is drawing colored shapes.
