Abstract: A method and apparatus for determining an error in global navigation information are provided. The apparatus includes at least one memory including computer executable instructions and at least one processor configured to read and execute the computer executable instructions. The computer executable instructions causing the at least one processor to detect a position based on a global navigation information, determine at least one from among a lateral error and longitudinal error at the detected position based on high resolution mapping data, determine an adjustment value based on determined at least one from among the lateral error and the longitudinal error, and transmit or store the adjustment value and the detected position corresponding to the adjustment value.

Abstract: A system and method of providing elevation information to a vehicle, the method including: maintaining a map matching software system at a remote server facility, wherein the remote software system includes a geographical map database storing geographical maps; receiving an elevation correction request from the vehicle, wherein the elevation correction request includes current vehicle location information; in response to receiving the elevation correction request from the vehicle, extracting elevation information from the geographical maps based at least in part on the current vehicle location information; and after extracting the elevation information from the geographical maps, sending the extracted elevation information to the vehicle, wherein the extracted elevation information includes elevation information concerning an area at or near the vehicle or along a pathway of the vehicle.
