CMPalmer writes “This may be old hat to most, but I’ve posted an example of using GPS tracklogs and Google Earth to virtually recreate vacation trips. I uploaded the GPS tracks into Google Earth so I could visualize them. One of the coolest tricks that Google Earth does is to let you “fly” along the tracks at any speed and altitude that you wish, so I can virtually recreate each drive over 3D scenery overlayed with satellite photos. This would have been great to do real time while I was there, because I was extremely frustrated to find that I had missed wonderful things that I drove right by or were just a few blocks away from.” Link.
