导线测量中起始坐标方位角的计算新方法

A New Method for Calculating Starting Coordinate Azimuth in Traverse Survey

根据连接角旋转导线定向点,采用实用通式直接计算导线测量中起始边的坐标方位角,避免了在坐标方位角推算过程中必须根据左角或右角而选择不同公式进行的计算。无论是在计算速度还是计算准确性上,本文的方法均要优于传统方法。

Orientation point is rotated according to tie angle firstly.Then starting coordinate azimuth is calculated directly using practical general formula.The choosing of different formula according to the different direction of tie angle should be avoided.The method discussed in this paper is faster in calculation speed and more accurate than traditional methods.
