Abstract:
    A map data base management system comprises a map data base storage unit, a map data file, a map management unit and a display unit. Accordingly, the present invention manages the map data involving the maps of various scales via the formalized index structure and the hierarchical structure. Thus, the size of the map index file can be minimized and the search of the map data can be simply performed via simple calculation. Also, a region is classified into one having land and the other having no land in each scale, which can enable constitution of the map data base with only geographically useful map data. Thus, a map data base can be efficiently constructed.
