Abstract: In a point-of-interest (POI) icon display method for displaying a POI icon at a position of a point of interest on a map, when a large number of POI icons are densely displayed, one representative icon is displayed instead of these POI icons. When the representative icon is selected, the original individual POI icons or detailed information of the POIs corresponding to the original individual POI icons are displayed. In a case in which a POI is displayed by a polygon on the map and the POI icon is present within the POI polygon, the POI icon is displayed in the central portion of the polygon.
Abstract: When specifying a Point of Interest (POI) as a destination in a navigation system, a relation between a POI and associated POIs is defined as a parentage. Detailed information such as polygon data, address, position, etc., is stored for a POI, and if the POI is a parent, a list of the child POIs or polygon data thereof also is stored. In setting a destination, the navigation system: (1) displays the detailed information and the polygon of the parent, and when a parent POI is selected from the POI list, (2) displays a list of the child POIs or polygons of the child POIs as requested, and (3) specifies a child POI from the list of the child POIs or the polygons of the child POIs to input a destination.
