Abstract
A reverse geocoding device includes a database that stores polygons and meshes in association with each other, and a search unit. The search unit inputs position information and search accuracy, and converts the position information into a mesh having a size depending on the search accuracy. The search unit searches the database for a polygon associated with the obtained mesh, identifies a polygon corresponding to the position information from among polygons obtained by search, and returns information given to the polygon.
