| Abstract: | This paper analyzes the principle,error sources and precision of triangulated height surveying,points out the key problems about first order leveling replaced by triangulated height surveying;and for the first time puts forward that in some given conditions,it is not only feasible but also valuable to replace first order leveling by precise triangulated height surveying,and proves it by experimentation as well. |

| Keywords: | electronic distance measurements triangulated height surveying first order leveling deformation monitoring surveying |
