摘要
介绍了一种坐标反算时的方位角计算方法:首先根据两点间的坐标计算得出坐标增量,用坐标增量计算出边长和1个过渡角,并根据纵坐标增量ΔX的符号判断方位角与该过渡角之间的关系,从而求得坐标方位角。实践证明,该方法可以减少象限判断的步骤,便于编程计算。
This paper introduces a kind of azimuthally calculation method by means of coordinate inverse calculation. The paper, first, puts forward to calculate the coordinate increment according to increment of coordinate between two points, and to use the coordinate increment to calculate the side-length and a transition angle. On the base of symbol of x - axis＇ increment △X, consequently calculates the azimuth. This method can abridge the steps of and is easy to program and calculate.
