Abstract:
Physical storage and organization of navigating digital map data are studied for the requirement of navigation service in embedded system. After comparing different physical storage realization methods of navigating digital map,i.e., embedded database method and file system based method, the file system based realization method is employed. Logical structure of navigating digital map’s physical storage is addressed and a multifile method is put forward to realize the data storage. According to the importance of index and location of navigating geographic elements, a data management frame based data index method is studied. Based on binary file, the definition of the physical storage format is expounded. Experiment results show that the physical storage method described in this paper is able to meet the performance requirements of navigation system and can well support the realization of navigation functions, being suitable for navigation service system.
