    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.
