摘要
由于在高海拔湿地内进行常规水准测量难度较大,且精度难以保证,由此对高海拔湿地进行GPS高程测量的优点进行介绍,对1个测区的GPS网的高程精度进行分析,并提出在同类地区进行GPS测量的几点看法。
Because of the difficulties of carrying out normal leveling being bigger, and the precision being difficult to assure, so this paper introduces the advantage of GPS height and analyzes a survey area of GPS height measurement precision, and puts forward some opinions about GPS height measuring on wetland.
