Abstract

Based on the analysis of the principle of triangulation elevation measurement, this paper deduces the strict triangulation elevation measurement formula, analyzes the influence of each error source on the accuracy, especially the influence of spherical air difference on the accuracy, and puts forward suggestions to reduce the error. And through the analysis and comparison of the accuracy of various methods of triangulation elevation measurement, it is concluded that different methods of triangulation elevation measurement in different environments have their own advantages and disadvantages, so as to replace leveling in specific environments and reduce workload, which has practical significance.
