I was invited to give a presentation on mapping to the local chapter of the Online News Association a while back. You can see it online here.
I used the reveal.js framework to get it online, so you can see an expanded version of my notes for most slides by using the down arrow on the keyboard or by clicking the down arrow in the presentation.
I drew most of the slides with my iPad + Pencil. Initially I was using it to brainstorm, and then thought, why not just make these the slides. I think it turned out ok.
