摘要:
A map difference data generation apparatus includes: most recent and supplementary map data storage devices storing primary most recent and supplementary map data, respectively; a map update reflection device generating secondly most recent and supplementary map data according to an update of a first link, and generating tertiary most recent and supplementary map data according to an update of a second link; a determination device determining a dependency relationship between the update of the first and second links, in accordance with results of searching a route in the tertiary most recent and supplementary map data between first and second nodes, which are both ends of the second link; and a map difference data generation device generating map difference data, which defines a combination of the update of the first and second links, when the update of the first and second links have the dependency relationship.
