Automotive OEMs, location-based service providers and end-to-end mapping solution providers use different methods for keeping maps up-to-date. These methods include updating the full map, the tiles or only the data vectors (layers). With such methods, OEMs must incur tremendous costs due to map size which affects the throughput, required bandwidth and on-boards storage.    HARMAN OTA Smart Delta updates for maps greatly reduces these costs.
