摘要
应用地图投影学、大地测量学及GPS网平差理论,针对超长线路测量中实测桩间距离与GPS反算边长较差过大的问题,结合贵广直流500千伏送电线路工程实例,给出了用Lambert等角切圆锥投影解决该问题的方法。
With the theories of cartography, geodesy and the method of GPS network adjust, take the gui-guang direct-current 500kV electric transmission line project as a case, the problem which the differential distantence value between electronic distance and GPS distance in long linear surveying are too big has been solved by using the Lambert projection.
