Abstract
A method and apparatus for searching polygon objects defined by polygon data in the map database of a navigation system when such polygon objects are not associated with any POIs. The method includes the steps of creating a data table which arranges information on the polygon objects in the map database based on polygon names, creating a data table which arranges information on the polygon objects in the map database based on polygon locations, prompting a user to specify a desired polygon object through a screen of the navigation system either by a polygon name or a polygon location, retrieving candidate polygon objects from the corresponding data tables that match inputs specified by the user and displaying a list of the retrieved polygon objects in a predetermined order, and allowing the user to finalize selection of the desired polygon object.
