Patent ID: 8775074

Claim:
A method of refreshing location code data, comprising: receiving a first message identifying a first map vendor and a map version of a first map database, wherein the first message includes map change data in a format associated with the first map database and specifies a removed road link and a new road link; receiving a second message identifying a second map vendor and a map version of a second map database, wherein the second message includes map change data in a format associated with the second map database; converting the format associated with the first map database and the format associated with the second map database to a common format; determining whether the map change data affects a location code stored in a location code system, wherein the location code links geographic coordinates to content for the first map vendor and the second map vendor; updating location code data associated with the location code based on the map change data by removing a reference to the removed road link and attaching the new road link to the location code; and storing the updated location code data in the location code system.
