Abstract
A map data providing system stores map data including multiple section data in which a reference point indicated by absolute coordinates is set for each of multiple sections, and a map element is represented by relative coordinates to the reference point of the section to which the map element belongs, detects position coordinates of the vehicle based on a navigation signal, employs a difference between absolute coordinates of the map element indicated by the map data and absolute coordinates of the map element identified based on the relative position of the map element and the position coordinates of the vehicle as a deviation amount, calculates a correction amount based on the deviation amount, corrects the position information of the reference point by using the correction amount, and creates corrected map data indicating position coordinates of the map element.
