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.
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。
