中文摘要: 为满足嵌入式系统中电子地图显示、导航的需要,研究了电子地图的数据组织与存储,提出采用地理数据分块实现数据的存储,并针对地理数据的存储方法所造成的数据不连贯性,研究了数据断点的处理方法。试验结果表明,研究的数据动态组织方法大大提高了地图显示的速度及数据连贯性。
Abstract:Data organization and storage of digital map are studied for the demand of digital map display and navigating service in embedded systems. A map data method is put forward to realize the data storage. Due to data inconsistency in map data storage method, the approach of handling data breakpoints is studied. Experimental results show that dynamic data organization method greatly improves the speed and data consistency of in map display.
