Abstract
In a map database site 1, a road network data is constructed in a road network database 110. A locus data is acquired every time by a location data receiving section 111. The road network data and the locus data are compared/collated with each other. The map information containing road information is updated provisionally and decisively. In this configuration, a change in a road situation and foundation of a new road can be dealt with and maintenance of the map data can be easily made.
