STORAGE MEDIUM, MAP INFORMATION PROCESSING DEVICE, DATA GENERATION METHOD

摘要

The purpose of the invention is to provide a technique with which a desired search can be implemented even in the absence of polygon data. From mesh regions M1 into which a region on a map has been divided, mesh regions M1 in which points of interest (POI) 22 are disposed are grouped by administrative district to define administrative district areas 23, and the administrative district areas 23 are extended to define extended administrative district areas 24. A data storage unit 15 stores, as search data 15b, data mapping the name of an administrative district to a POI 22 within the extended administrative district area associated 24 with said administrative district.
