摘要
GPS由于具有作业精度、作业效率高等特点,正逐步取代导线测量而成为线路工程平面控制的一种重要方法。文章探讨了GPS建立线路平面控制测量的方案并以具体的工程案例验证了方案的可行性。
GPS has the characteristics of the high precision of the operation, operation efficiency,which is gradually replacing the traverse line horizontal engineering control and becoming an important method. This paper discusses the establishment of GPS route plane control measurement scheme with spe cific engineering case to verify the feasibility of the scheme.
