This past weekend, a couple of Googlers headed up to Lake Tahoe, CA with a few GPS devices. And recorded some of their favorite ski runs and animated tracks in Google Earth. You can now check out all of animated tracks in the video below,
or download the KML to play the tracks in Google Earth.
Capturing a GPS track is easy -- just make sure that you have a GPS tracking device on hand before you hit the slopes. A Garmin or Magellan device works best, but you can also use a GPS tracking application on most mobile phones. My Tracks on Android works well, or if you have an iPhone, try using MotionX-GPS.
