I still like this; gps for dummies.http://gizmodo.com/5636541/contour-adds-integrated-maps-into-its-helmet-cam-videos
Scroll down and look at their demonstration video. Be sure to go to full screen!
"...the ContourGPS adds a second round to the helmet-cam pissing match: Integrated (wait for it) GPS with a map embedded in the video...
The software, though, is where this new addition really impresses: there's a wee Google Map snuggled up next to any video you shot with the GPS activated. It shows the route you took, your elevation, speed, and your progress in relation to what's going in the video. If you edit, the map adjusts to compensate. Even if you edit in Final Cut or iMovie, the video coding is smart enough to log your cuts and and adjust the map when you import the movie back onto Contour's website, an online community you will probably only use to get the embed code with the map thingy included.
But you'll probably use it, because that map is the ultimate bragging right. And bragging is kind of what it's all about. Contour plans on staging virtual competitions, where camera owners race the same run at different times, and compare their times on the Web. After all, the GPS will go a long way towards keeping competitors honest. And there's no reason why you couldn't compete against your friends either, wagering beers over who had the fastest top speed or who caught the most air—all factors the Contour's GPS can clock.
