Penn State University kicked off a new four-part series this week, entitled The Geospatial Revolution Project. It's an examination of modern mapping, focusing on GPS, taking a particular look at GPS's impact both on our daily lives and on the world at large. There's more to GPS than finding the nearest Trader Joe's with a Google  Maps app, it turns out.
The first episode, a 13-minute mini-documentary that's viewable on YouTube, takes a brief look at a timeline history of mapping before diving headlong into one of the most striking uses of GPS in the last decade: Providing humanitarian aid during the Haiti earthquake relief efforts . Despite the destruction wrought by the earthquake, about two-thirds of phone lines remained standing--the most resilient bit of infrastructure--and that allowed some ingenious rescue methods that would have been impossible even a few years earlier.
In the days after the earthquake, geographical information experts came up with some fairly stunning ways to help get aid to those who needed it, providing an SMS service, maps, and translators in an open, crowd-sourced system that allowed those in need to text their location in Creole and have English-speaking volunteers in the States route their requests through the appropriate channels. We covered some of those efforts, which you can read about here .
It's a really well-made video, though some of the wonder at simple consumer smartphone features (the smartphone can find nearby Starbucks! What a world!) is a bit excessive. Still, as a more modern and topical companion piece to efforts like BBC's "The Beauty of Maps," it's very compelling. The first episode is available now, and the following three will be released every few months (the next is due on November 2nd). You can watch it on YouTube  or at Penn State's official site .
