Zusammenfassung:	PROBLEM TO BE SOLVED: To make it possible to rapidly and efficiently make a navigation system using different types access and to improve the performance of the navigation system by interleaving a parcel of a data record of a first type with a parcel of data record of a second type. SOLUTION: Intermediate format files 902 separated by each of the respective data types and layers are formed by starting from a geographic data base 900 supplied in a universal data format. After the separated intermediate format files 902 are formed, the intermediate format files 902 are parceled and the parcels 906 of the data records of the respective data types are formed. When the separated parcels 906 by each of the respective types and layers are formed, the parcels by each of the respective types and layers are connected to the single file. Namely, the parcels are selected from the two or more parceled intermediate format files 906 and are subjected to interleaving.
