Google Earth路径信息提取至CAD技术研究

摘要

The route is first selected from Googel Earth combined with satellite maps, and then the coordinates of each turning point in selected route are exported into CAD to automatically generate vectorgraph, the project route map is finally generated combined with topographic maps,.%在Googel Earth中结合卫星地图进行选线，并将选出的线路各个折点坐标导出至CAD中，自动生成矢量图，与地形图吻合，生成工程线路走向图。
