摘要
GPS-RTK高程测量的主要方法是坐标转换和高程拟合。本文主要结合某线路介绍了坐标转换方法以及如何对其测量成果进行检核。常规的高程检核方法是比较联测水准点高程和GPS-RTK测量高程,而本文结合线路作业的特点提出了利用直线或平面拟合方法对线路基于坐标转换法获得的GPS-RTK高程测量成果进行检核,结果表明本文的方法是可行的。
Coordinate transformation and height interpolation are the main methods for GPS-RTK height surveying.This paper introduces the coordinate transformation and how to validate the results of GPS-RTK height surveying. The conventional method for validating height is the comparison the height of the connected leveling points and GPS-RTK points. A method for validating GPS-RTK height results based on coordinate transformation by means of line or plane height interpolation is given out in this paper.The results show this method is feasible.
