A polygon retrieving method includes converting a random polygonal area indicating a shape of each lane of a road within a predetermined unit area on a map into polygonal information indicated using coordinates of vertexes of the polygonal area and storing the polygonal information in the storage in association with a unit area, specifying temporospatial information including positional information corresponding to coordinates within the predetermined unit area on the map, and extracting all temporospatial information including positional information corresponding to coordinates inside a polygonal area indicated by the polygonal information associated with the unit area among the specified temporospatial information, by processing circuitry.
