Abstract

A method and system for refreshing location code data is disclosed. The system includes a location code change system that receives map change data and location code change data. The location code change system processes the map change data, finds affected location codes, and updates the location code'"'"'s information by manipulating the location code data or performing a geocoding operation. The updated location code data is stored in a location code system. The location code change system receives the location code change data from the location code system and provides information regarding the location code changes to a map change system, which facilitates map updates based on the location code changes.

Claims

1. A method of refreshing location code data, comprising:

receiving a message that includes map change data for at least one map database, wherein the message identifies a map vendor and a map version associated with the at least one map database;

determining whether the map change data affects a location code stored in a location code system;

updating data associated with the affected location code based on the map change data; and

storing the updated location code data in the location code system.

2. The method of claim 1, further comprising authenticating the message to identify specifications for at least one of the map vendor and the map version.

3. The method of claim 1, further comprising transforming the map change data based on rules specified for at least one of the map vendor and the map version.

4. The method of claim 1, wherein determining whether the map change data affects the location code data includes examining the map vendor, the map version, and a map change type.

5. The method of claim 1, wherein updating data for the affected location code includes performing a forward geocoding operation if the affected location code contains address information.

6. The method of claim 1, wherein updating data for the affected location code includes performing a reverse geocoding operation if the affected location code does not contain address information.

7. The method of claim 1, wherein updating data for the affected location code includes using the map change data to manipulate the location code data.

8. The method of claim 1, further comprising performing a map baseline shift if the location code data includes data for a number of map versions that exceeds a predetermined amount.

9. The method of claim 8, wherein the map baseline shift includes deleting the location code data for map version associated with an oldest date.

10. A location code change system used for refreshing location code data stored in a location code system, comprising:

a map change receiver operable to receive messages that include map change data, wherein the map change data identifies a map vendor and a map version associated with the map change data;

a map change processor operable to transform the map change data obtained by the map change receiver into a common format; and

a location code updater operable to identify location codes affected by the map change data using the common format and update the affected location codes, wherein the location code updater sends a message to the location code system that includes updated location code data.

11. The system of claim 10, further comprising a map change requester operable to request the map change data.

12. The system of claim 11, further comprising a map change scheduler operable to signal the map change requester to request the map change data.

13. The system of claim 10, further comprising a map change queue that stores the transformed map change data prior to the location code updater identifying the affected location codes.

14. The system of claim 10, further comprising a geocoder operable to perform geocoding operations for the location code updater.

15. The system of claim 14, further comprising a geocoder data store that stores geocoding data used by the geocoder.

16. The system of claim 10, further comprising a location code change receiver that receives messages from the location code system that includes location code change data.

17. A data refresh system for updating location code data, comprising:

a map system that includes storage, programs, and interfaces for changing map data in a map database;

a map change system that receives messages from the map system that includes map change data, wherein the map change system formats the map change data to be compatible for other systems;

a location code change system that receives the formatted map change data from the map change system and updates location code data based on the formatted map change data; and

a location code system receives updated location code data from the location code change system.

18. The system of claim 17, wherein the location code system sends messages to the location code change system that includes location code change data.

19. The system of claim 18, wherein the location code change system sends the location code change data to the map change system.

20. The system of claim 19, wherein the map change system sends the location code change data to the map system.
