Abstract: It is an object of the present invention to provide a technique by which a desired search can be performed even without any polygon data. An administrative district area is defined by collecting mesh areas in each of which a POI is located, for each administrative district, among mesh areas obtained by sectioning an area on a map, and an extended administrative district area is defined by extending the administrative district area. Then, the data storage stores therein data in which a name of an administrative district is associated with a POI within the extended administrative district area related to the administrative district, as search data.

Abstract: Map data is managed by being divided into a geometric information data list of pieces of geometric information or a phase information data list of pieces of phase information, an attribute information data list of pieces of attribute information, and a relation information data list of pieces of relation information each indicating a relation between the geometric information or the phase information and the attribute information.
