System and related method for offering navigation guidance

摘要

A method of providing navigation guidance information to a user of a portable electronic device includes uploading a track file to a server, the track file containing a plurality of waypoints that form a track, adding a plurality of navigation points to the plurality of waypoints to produce a modified track file, the plurality of navigation points providing navigation guidance to the user of the portable electronic device, and the plurality of navigation points containing data for creating a graphical depiction of intersections associated with the turn-by-turn navigation guidance. The method further includes downloading the modified track file to the portable electronic device, and providing bi-directional turn-by-turn navigation guidance to the user of the portable electronic device when the user reaches each of the plurality of navigation points as the user follows the path indicated by the modified track file.

主权项

1. A server for adding navigation guidance information to tracks, the server comprising:
a memory storing a map database comprising geographic data; a transceiver receiving a track file uploaded to the server, the track file containing at least three user-defined waypoints that form a track; track processing software modifying the track file to produce a modified track file, the modified track file comprising the at least three user-defined waypoints and a plurality of navigation points, the plurality of navigation points being generated according to the map database and containing navigation data providing bi-directional turn-by-turn navigation guidance to a user of a portable electronic device storing the modified track file when the user of the portable electronic device follows a path indicated by the modified track file, and the plurality of navigation points containing graphical data for creating a graphical depiction of intersections associated with the turn-by-turn navigation guidance, wherein each navigation point of the plurality of navigation points comprises data indicating a distance from the navigation point until an intersection to which the navigation point corresponds; and a processor executing the track processing software, controlling the transceiver to output the modified track file, and controlling operation of the server.
