Research for Incremental Update Data Model applied in Navigation Electronic Map

Most of the present Car Navigation systems are usually update data off-line, which does not satisfy the high verisimilitude requirements in Navigation Electronic Map applied in vehicle navigation and some advanced driver assistance systems. Based on this problem, this paper presents the Static and Dynamic Incremental Data-Update model for Navigation Electronic Map. With the resources-saving, this model could improve the update efficiency, provide a high performance-cost-ratio and satisfy the high verisimilitude requirement.
