| 摘 要： | 为实现精准的移动导航定位,将离线地图导航软件与web墨卡托投影格式影像图、DEM数据、OSM矢量交通图等数据相结合,借助离线地图导航软件的定位功能以及地形地貌、植被类型、通行通视条件等特征信息进行移动导航定位的现场解译,同时总结了移动导航定位在广西某输电线路和老挝某钾盐矿项目勘测中的导航应用效果。结果表明,基于离线卫星地图的移动导航定位既可以帮助野外工作人员宏观把握整体导航路线,又能通过现场解译对临场细节进行验证,从而优化导航线路顺利到达待测点位置。

| Abstract: | In order to realize accurate mobile navigation and position，the authors combines the offline map software with the data such as the imaging map based on web Mercator projection，DEM data and OSM vector traffic map，and uses the position function of the offline map software and the characteristic information such as topogra- phy，vegetation，pass and sighting conditions to realize on-site interpretation of the mobile navigation and position． At the same time，the authors summarize the results of the application of the mobile navigation and position in the surveys of one transmission line in Guangxi and one potassic salt ore in Laos． The results show that the mobile navi- gation and position based on offline satellite map can not only help the field workers to master the whole navigation route but also verify the on-site details through the on-site interpretation，thereby，the navigation route can be opti- mized to reach the position of the unknown points smoothly． |
