| 摘 要： | 全站仪三角高程测量可以代替水准测量进行高程控制,主要有对向观测法和中间观测法。在这两种方法中,前者将大气折光系数作为常数考虑,认为各个方向的折光系数相同,这与实际的情况有出入。而中间观测法则将大气折光系数作为变量处理,并加以改正。本文详细介绍了这两种方法的具体实施过程,并对其精度进行了分析。

| Abstract: | Triangle elevation with total-station can be used for control survey replacing leveling,which contains the double-direction observation method and midpoint observation method.The prior takes the atmospheric refraction coefficient as constant,while the latter does it as variable.The paper introduced the progress of above two methods and made detailed analysis about the accuracy of them.The result can be inferred in practice. |
