Intelligent reverse geocoding
Methods and apparatus, including computer program products, for obtaining location information from a location source. A geographic reference point is determined based on accuracy of the location information. The geographic reference point is incorporated into a location result.
1. A location server system, comprising:
a ranker to receive current location information from a physical wireless device;
a point of interest map database, in communication with said ranker, to provide said ranker with a point of interest within a geographic region including said current location;
a street network model database, in communication with said ranker, to provide said ranker with a closest road segment within said geographic region; and
a civic address database, in communication with said ranker, to provide said ranker with a closest civic address within said geographic region;
wherein said ranker adjusts an accuracy of said current location by incorporating into said current location a closest geographic reference point selected from among said closest point of interest, said closest road segment, and said closest civic address; and
wherein a size of an icon on a mapped display indicating said current location is adjusted based on said adjusted accuracy of said current location.
2. The location server system according to claim 1 , wherein said closest geographic reference point comprises:
a nearby road segment.
3. The location server system according to claim 1 , wherein said closest geographic reference point comprises:
a point of interest (POI).
4. The location server system according to claim 3 , wherein:
said ranker determines said closest geographic reference point based on a point and polygon search of a location shape as overlaid on a point of interest map.
5. The location server system according to claim 1 , further comprising:
a transmitter, in communication with said ranker, to transmit said adjusted-accuracy current location to a client device.
6. The location server system according to claim 5 , wherein said client device comprises:
a mobile device.
7. The location server system according to claim 5 , wherein said client device comprises:
an automobile navigation system.
8. The location server system according to claim 1 , further comprising:
a shape icon determination module to obtain a shape icon representing said adjusted accuracy of said current location of said physical wireless device, said shape icon being sized both according to a degree of accuracy of said current location, and according to a proximity of said current location to said closest geographic reference point.
