I actually saw one that I think you'd be interested in checking out, it's all about cartography and map-making. I was going to pick it up myself, but when I was looking it up I couldn't find many videos on the software itself or how to use it, so I'm going to look into it a bit more before purchasing.
Thanks for the re-blog.
I think having prior skills and knowledge, like programming, would be a major help, but I'm not sure really.
One of my buddies snagged this and it sounds like a great deal. He said the software is a little dated for UI, but it works really well. I will probably snag it as it definitely is something I'm interested in.
