| Abstract: | This paper analyzes the theory,error sources and precision of underground trigonometric leveling,points out that the error of using steel rule to measure the height of instrument and prism has a great impact on trigonometric leveling;and puts forwards an algorithm of Multielement Linear Regression for reducing the error impact,then corrects the measuring results by experimentation.It is shown that the algorithm for improving the precision of trigonometric leveling is feasible. |
