摘要
根据导航电子地图的内容和更新特点,提出基于现势性较强的导航电子地图更新地形图的方法。利用MapInfo中Tab格式的1∶1万导航电子地图对ARC/INFO中cover格式的1∶1万地形图道路、居民地、植被、水系等变化较快的人文要素进行了更新。通过试验充分验证,文中提出的技术方案是可行的。
On the characteristic of electronic map for navigation,this paper firstly presents a method using electronic map for navigation to update topographical map.Then,with 1:10 000 electronic map(the format is Tab of MapInfo Company),it finishes the update of 1:10 000 topographical map(the format is cover of ARC/INFO),especially updates road,residential area,vegetation,and river etc.Experimental and analytical results show that using electronic map for navigation to update topographical map is feasible,and the method can reduce the cost as well as shorten the period.
