Abstract: In the case that a road is updated in units of specific areas in order to reduce the amount of communication data, the quality may degrade; for example, a network of roads is disconnected. To solve this problem, alterations to map data are grouped into map update data of the unit in which a network of links to update connects, and an ID is assigned to each map update data. Also, the map update data that may cause disconnection and the map update data that connects the connected components are detected from among all the past map update data, and these map update data are distributed so that they are always applied at the same time.
