摘要
对于难以获取基础地理信息的区域,以及纸质地图地物信息缺失的区域,提出基于ASTER GDEM数据和卫星遥感影像图的公路选线方法,并最终将路线线位导入手持GPS设备进行外业调查,不仅能提高工作效率,而且节约前期勘测成本。
The methods for highway route selection based on ASTER GDEM data and satellite remote sensing image map are put forward for the regions that are hard to obtain basic geographic information and lack ground feature information of paper map, and fieldwork investigation is made at last by leading - in handheld GPS device for route position, which can not only improve the work efficiency, but also save the cost of early - stage reconnaissance and design.
