Penn State's "Maps and the Geospatial Revolution" Offered through Coursera.org Starts April 30th, 2014!
I took this program last year and it was a good refresher. I'd highly recommend it to those interested in getting into G.I.S. and those looking to expand their resume with a verified certificate. Check it out Maps and the Geospatial Revolution!
Additionally I'd be happy to answer questions about my experience with the course and I'll likely be taking again this year for a verified certificate.
