Frequent readers of this blog know that I am a trail and GPS enthusiast. If you are interested in combining photography and GPS data for compelling presentations in Google Earth, be sure to check out Life of a Geolocated Blog Post.
This excellent article describes exactly how to combine photography of various points in an area (say a hiking trail) and GPS tracking information to create a depiction of your trip in Google Earth or Google Maps. See some examples of this technique in action (be sure to click the Google Earth/Maps geotag links at the end of the articles). Very cool, eh?
