%X With the tremendous development of computer technology and Geoinfomatics, more people are taking vehicle navigation system (VNS)as one of their travelling assistant tools when auto-dependant lifestyle has become more popular worldwide. Digital navigation map is fundamental part for VNS, so map data actuality will directly exert an influence on navigation accuracy. We find that data updating mode just depending on CD or intelligent memory card is a big bottleneck for data updating from present navigation map data production method and procedure, management mode and updating approach in navigation terminal. Therefore, this paper is based on on-demand dynamic data updating in vehicle navigation application and will study navigation data model with the support of updating, change detection approach for incremental navigation data between different data versions and dynamic data updating modest. An experiment system is designed to prove related algorithms and procedure. It will be an important innovative research for map production and efficient use in navigation industry, which can also extend navigation information services, mitigate urban congestion and provide technology for intelligent transportation system.
