  • Methods and systems for reconstructing tracks using electronic map data
    Patent number: 9816831
    Abstract: A method and system for generating a route reconstructing a track through a navigable network in an area covered by an electronic map is disclosed, wherein the track is represented by an ordered series of point locations. One or more of the point locations are selected and an area is defined and associated with each of the one or more selected point locations. The ordered series of point locations and the defined areas are used to determine a plurality of polylines, and, for each of the polylines, a first route is generated based on the respective polyline. A second route is generated through each of the defined areas connecting the respective first generated routes. The route reconstructing the track comprises the generated first routes and the one or more generated second routes.
