城市二级光电测距三角高程导线精度分析

Accuracy analysis of secondary electronic trigonometric elevation traverse for urban

本文对城市二级光电测距三角高程导线的误差来源进行了分析,并对其精度进行估算。根据实例分析,证明了城市二级光电测距高程导线可以代替五等水准测量。

This paper analysed error sources based on the secondary electronic trigonometric vertical traverse for urban.At the same time accuracy estimation was made.In the end,it was proved that the method could replace the fifth grade leveling by a case study.
