METHOD AND SYSTEM FOR FINDING PATHS USING GPS TRACKS

摘要

Systems, methods, and machine-readable media for refining mapping data are provided. One or more candidate routes may be identified based on input location coordinates of a mobile device. The one or more candidate routes may be compared to previously stored mapping data, and based on the comparison, a route score for each candidate route may be calculated. Based on the route score, a route most likely traveled by the mobile device based on the input location coordinates may be selected. The candidate route most likely traveled by the mobile device user may be analyzed to determine whether it contains a transition segment between one location coordinate and the next location coordinate in the input location coordinates that is not along a existing path known to the previously stored mapping data. The transition segment which is not part of the previously stored mapping data may be identified as a missing path of the previously stored mapping data.
