摘要
随着全站仪的更新换代,全站仪三角高程的测量精度不断提高,其应用领域在不断地扩大和深化。本文着重对单向观测法、对向观测法、中间设站法等三种三角高程测量观测方法进行论述和精度分析,对主要误差来源进行综述,并对其应用领域进行了总结,得到了一些有益的结论。
Along with the upgrading of total station, the accuracy of triangle elevation surveying of the total station goes on improving and its application field is constantly expanding and deepening. This article emphatically analyzes the accuracy of the method of trigo- nometric leveling of single observation, reciprocal observation and mid free station. This paper also summarizes the main error sources of the trigonometric leveling and the field of its applications and some useful conclusions are obtained.
