摘要
本文根据对实测资料的分析,讨论红外测距仪三角高程测量代替几何水准问题。得到的结论是,如适当控制测边长度且以1秒经纬仪往返观测天顶距2个测回,则代替三、四等水准测量是可行的。
This paper discusses the possibility of using EDMI for the third or the fouth order levelling survey instead of geometric levelling. The conclusion is positive if ranging length is controlled and 1 sec. theodolite is employed to measure vertical angle repeatedly.
