More Efficient Incremental Map Updating System for Navigation Systems

Several map update systems that utilize Telematics services have been introduced. Those map update systems can be categorized into two major methods. They are "Element-by-element map update" and "Map update by partial replacement." The "Element-by-element map update" ensures the connectivity of map data network after completing the update. Alternately, the aim of the "Map update by partial replacement" is to provide the updated map to end users quickly. General "Element-by-element map update" systems require post-processing to re-create the map database using the existing map database along with the update information after receiving the update in order to retain the map network quality. DENSO CORPORATION has developed a new "Element-by-element map update system" that does not require the re-creation of map database in post-processing. This system provides the advantages of both methods; getting updated map information to end users in a short period of time while retaining the network connectivity.
