“角度前方交会”是通过观测角A和角B求出点P坐标的定位方法；“方位角前方交会”是通过观测方位角AP和BP求出点P坐标的定位方法。
用前方交会法进行位移监测是测量中常用的方法。
Forward intersection survey is the common method in displacement monitoring.
前方交会解算像点坐标，一个很好的程序，希望大家喜欢！
Forward intersection point solves such as coordinates, a very good program, I hope you like!
笔者提出从测角前方交会推演出测边解算前方交会的简便公式，方便可行，比较实用。
A simple formula of side-measured forward intersection is derived from angle-measured forward intersection, which is easy, feasible and practical.
