Abstract

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.
