8. The method of claim 7 , and further comprising replacing the corpus GPS waypoint with the updated GPS waypoint.
7. A method for increasing route accuracies, the method comprising: receiving a first GPS waypoint and a first position accuracy prediction (PAP) parameter associated with the first GPS waypoint, wherein the first PAP parameter comprises a first quality parameter set having a first weight value, a first confidence value for the first GPS waypoint, and a first error distance for the first GPS waypoint; comparing, with a computer processor, the first PAP parameter to a corpus PAP parameter associated with a corpus GPS waypoint, wherein the corpus PAP parameter comprises a second quality parameter set having a second weight value, a second confidence value for the corpus GPS waypoint, and a second error distance for the corpus GPS waypoint, wherein the comparing step comprises: calculating a weight average based on the first and second weight values; computationally extending the first error distance from the PAP parameter of the first GPS waypoint to provide a first probability distribution circle; computationally extending the second error distance from the PAP parameter of the corpus GPS waypoint to provide a second probability distribution circle; and computationally generating a vector line between the first GPS waypoint and the corpus GPS waypoint; and determining, with the computer processor, an updated GPS waypoint along the vector line between the first GPS waypoint and the corpus waypoint and within an overlapping area of the first and second probability distribution circles based on the calculated weight average.
