Provision of database objects for destination search by a navigation device

摘要

A technique for providing addressable database objects for route guidance by a navigation device to geographical areas is provided. A method implementation of this technique comprises providing a map database comprising at least area objects, wherein each area object is associated with an area name and a polygon representative of a geographical area, retrieving at least one area object from the map database, determining, based on the polygon associated with the retrieved area object, at least one destination point for route guidance to the geographical area, generating a point object comprising the area name associated with the retrieved area object and the at least one destination point, and making the first point object, or a database object derived therefrom, available for being addressed by the area name during a destination search.

主权项

1. A method of generating addressable database objects for route calculation by a navigation device to geographical areas, the method being performed during a map data compilation process and comprising:
providing, by an interface, during the map data compilation process, a map database including at least area objects, wherein each area object is associated with an area name and a polygon representative of a geographical area; retrieving, by a processor, during the map data compilation process, at least one area object from the map database; determining by the processor, during the map data compilation process and based on the polygon associated with the retrieved area object, at least one destination point for route guidance to the geographical area; generating, by the processor, during the map data compilation process, a first point object including the area name associated with the retrieved area object and the at least one destination point; making, by the processor, during the map data compilation process, the first point object, or any database object derived therefrom, a destination object for being addressed by the area name during a destination search; retrieving the at least one destination point expanded from the destination object during the destination search; and transmitting at least a portion of the destination object to the navigation device for display at a graphical interface on a display of the navigation device, wherein the at least one destination point is additionally represented with at least one corresponding graphic indicative of the at least one destination point.
