摘要
针对在山区等地方用几何水准测量进行高程传递十分困难的情况,本文提出了用精密三角高程测量代替二等水准测量的两个观测方案,讨论应采取的技术措施及一些注意事项,目的是为了削弱、改正大气折射等误差对观测成果的影响。
In view of the situation that height transfer with spirit leveling in mountain area is very difficult,this paper puts forward two kinds of the precise triangulated height surveying which instead of second-order leveling,and discusses some key technique and notices.The purpose is weaken and change the error to surveying result by astronomical refraction.
