Abstract
A method for increasing route accuracies, comprising receiving GPS waypoints associated position accuracy prediction (PAP) parameters, comparing the PAP parameters to corpus PAP parameters associated with corpus GPS waypoints, and updating the corpus PAP parameters and the corpus GPS waypoints based on the comparison of the PAP parameters to the corpus PAP parameters.
