摘要
在地形起伏较大的地区,采用全站仪中点法进行三角高程测量,能大大减少劳动强度,提高作业效率,有较强的实用性。基于此,本文从三角高程测量的原理出发,分析其误差来源及精度,最终通过实例验证了利用全站仪中点法替代二等水准测量的可行性。
When total station midway method used in trigonometric leveling,especially in the area of hypsography being biggish,this method can greatly reduce the labor intensity and enhance operational efficiency,and have more strong practicality.This paper is based on the basic principle of trigonometric leveling,through the analysis of their source of error and precision,at last this paper verifies the feasibility of the method for using midway trigonometric leveling of total station instead of second-order leveling.
