摘要
本文主要论述在河道测量中如何应用GPS高程测量,保证测量精度和可靠性的方法,同时通过某一河道实际测量过程中出现的问题进而对测量精度和可靠性进行具体分析。
With a practical example of the river measurement process,this paper discusses the method how to measure the river by GPS height measurement using global positioning system to ensure measurement accuracy and feasibility.
