中国导航电子地图的技术发展正处在瓶颈阶段,即地图的更新赶不上现实世界的更新速度。针对这个现状,本文从实际生产出发,介绍了如何在导航电子地图生产制作中利用遥感影像图进行数据制作和信息补充,从而提高生产效率,同时阐述了利用遥感影像进行电子地图更新所面临的问题。 更多还原

【Abstract】 The development of navigation electronic map is stepping into bottleneck stage,in which the update speed of map is slower than the change speed of real world.Based on the analysis of existing problem,we introduced a new way that can advance the production efficiency,that is use the remote sensing image to product map data and extract information.At the last of this paper,the authors point out the problems facing this technique. 更多还原
