A MOOC from Penn State
Last week I started Maps & Geospatial Revolution, a Massive Open Online Course from CourseRA. CourseRA delivers varied free courses for universities around the world.
It is a 5 week course. Given the first week took only a couple of hours, you could easily catch up. The quality of the course in both content and execution is so far excellent.
So if you want to learn more about maps and geography within the geospatial revolution then enrol now at CourseRA.
