PROBLEM TO BE SOLVED: To provide a method for generating a store data list in which a plurality of stores are integrated in accordance with the scale classifications of map data.SOLUTION: A data generation server 2 starts, from a storage data list in registration, processing of executing: a step (S12) of searching for a combination of unduplicated store data pieces from the list of store data pieces to be integrated; a step (S13) of calculating an inter-store distance from store coordinates included in the two combined store data pieces; a step (S14) of extracting the combination of store data pieces whose inter-store distance is shorter than an integration distance; a step (S15) of executing integration processing of generating a store data piece including the store coordinates determined from two store coordinates of the extracted combination; and a step (S16) of, when the number of store data pieces is not more than a preset value, storing the list of store data pieces at this point of time in association with scale classifications, and of, when the number of store data pieces is beyond the preset value, changing the integration distance and then going back to the step S12. |
