精密三角高程测量在跨河水准测量中的应用研究

From the precise triangulation principle, measurement method and accuracy analysis done in terms of trigonometric leveling a more detailed description of the precise source of error for triangulation, pushed to the jump point method and the accuracy of the observed estimate of the formula. On this basis, the errors obtained reduced to improve the accuracy of some conclusions. Height measured with a large number of statistical data, test analysis demonstrated by precise trigonometric leveling across the waters instead of measuring the feasibility of second grade level. Concluded that high-precision electronic total station under certain conditions can be replaced by trigonometric leveling First Order Leveling.
