Abstract
Methods, data structures, and systems provide techniques for processing track logs. A track log is represented as a plurality of track points. The track points represent geographic positions previously traversed. The track log and the track points are overlaid on a map and presented on a display in communication with a portable navigation device. Track points are graphically selected and identified via the display. Any graphically selected track point is also associated with a selectable operation for immediate, automatic, and/or subsequent execution on the portable navigation device.
