Abstract
Abstract A map data processing apparatus includes: a map data storage unit, a differential data input unit, and a map data multiple update unit. The map data storage unit stores map data. The differential data input unit inputs differential data representing the difference between current map data stored in the map data storage unit and the most recent map data in a script format for each version. The map data multiple update unit updates the map data in the map data storage unit to the most recent map data using the differential data corresponding to the version.
