Abstract: A device which converts geographic coordinates such as track logs to navigational routes matched to known road networks includes a GPS receiver; a display; and a processing system. The GPS receiver determines a series of geographic coordinates corresponding to points along a path traveled by a user of the device. The processing system accesses the series of geographic coordinates; compares them to a database of known paths to find a match; and displays at least a portion of the matching path along with navigational information which permits the user to generally follow the series of geographic coordinates while traveling on the path.
