Research and Application of Leveling-like Trigonometric Leveling using Total Station

Based on the research of the mathematical model of trigonometric leveling,combined with the performance of today's total stations,this paper derives from the new way of trigonometric leveling-leveling-like trigonometric leveling,using total station a mathematical model,and gives method of accuracy analysis and its applications.So this paper finds a practical,efficient,reliable new method with broad scope of application for height measurement.And so to rid itself of the following situation,that the height measurement below the third order can not be carried out without leveling instrument.
