PROBLEM TO BE SOLVED: To supply geographic information by an efficient, economical and flexible technique of wide use, onto a computer-readable storage medium, with one potential disturbance when imparting an intensified function to a navigation system.SOLUTION: A parcelization method supplies a parcel less than the maximum assigned data content but having a desired fill rate. The parcelization method also imparts a division sequence for facilitating address assignment and identification of the parcel. A common boundary set is used to limit all the spatial parcels (including a type such as a data set parcelized independently) so as to include one parcel within the other parcel completely, even in case of any type and any-two of spatial parcels. A data volume required for expressing a spatial parcel boundary within a global kd tree index is reduced by this manner.
