A pattern identification unit () identifies a predetermined pattern in the environmental map on the basis of the environmental map data. A corresponding element identification unit () identifies a linear element that appears in a map indicated by given map data provided by a given map service and that is associated with the predetermined pattern. A common environmental map data update unit () updates the environmental map data on the basis of a location of the linear element in the map indicated by the given map data.
