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.

Abstract: A vehicle navigation system includes: a route guidance element for searching an optimum route from a current position of a vehicle to a destination according to a normal map data and for guiding the optimum route by displaying the optimum route on a map screen image of a display; a deviation route retrieving element for retrieving a deviation route, which has a possibility that a user may deviate from the optimum route and enter into the deviation route although the vehicle is incapable of driving along the deviation route; and an attention notification element for outputting attention notification information in order to prevent the user from entering into the deviation route when the route guidance element guides the optimum route.

Abstract: A map data is disclosed. The map data comprises a link data and a segment data. The link data describes a characteristic of each link in a group of links on a link-by-link basis. The group of links forms a road network. The segment data relates to each segment in a group of segments on a segment-by-segment basis. The segments are defined in units of link string. Each link string is a string of multiple links and corresponds to a main road. Each link string terminates at least at an intersection of the main road. The multiple links are a part of the group of links. The segment data of each segment describes information on a storage destination of the link data corresponding to the link string that forms the each segment.
