摘要
坐标方位角反算是测量中最基本的计算之一,但传统的方位角计算方法涉及到象限问题,判断容易出错,尤其让一些初学者感到迷惘。为了使坐标方位角反算变得直观简单,提出了利用辅助角来计算坐标方位角的方法,并对其特点及应用进行了分析。
Inverse calculation of coordinate azimuth is one of the most basic calculations in surveying work,but the traditional method of azimuth calculation involves quadrant problem,making it not easy to judge and understand,which especially perplexes some beginners.To make coordinate azimuth calculations more intuitive and simple,this paper puts forward an auxiliary angle method applied to inverse calculation of coordinate azimuth,analyzes its characteristics and application.
