I'm looking to create a few world maps, might anyone know of any software or Photoshop brushes/styles I can use to do this? These maps are going to be multipurpose. I'll be using them to texture planets in Universe Sandbox as well as personal reference. So preferably I'd like to be able to make physical terrain maps so I can distinguish deserts and mountains as well.

Would this be of any use?

Basically - with regards to brushes - what she ends up doing is using Photoshop's brush settings to combine brushes until something land-mass-ey can be formed from it.
