My friend wants to make a map, and I have made lots of them. So he asked me what some good mapmaking techniques are. I said to him,
"Well, why would I tell you if I could tell the world?" So, here are some good mapmaking techniques. I don't want to waste all of my time listing and describing great mapmaking tools and techniques so here are some of the links to videos that taught me most of what I know and use today.
