Tip of the day, if you have a geotagged image file such as those produced using Location Tracker on Symbian phones, then you can use libferris to start Google Earth showing you that image on a map. Just run
with the image(s) you want to see. Its a fairly quick way to show the movements of the day on a map. I should also add timeline support there I guess, so you can retrace a trip in the order it occurred using just waypoint image files.
This also works with any type of file that is location tagged with libferris. If you have a digital long/lat then you can view it on a map (TM).
