描述
¥Description
获取两个 points 并计算它们沿恒向线的方位角,即以度为单位测量的与北线(0 度)之间的夹角。
¥Takes two points and finds the bearing angle between them along a Rhumb line i.e. the angle measured in degrees start the north line (0 degrees)
参数
¥Parameters
名称 | 类型 | 描述 |
---|---|---|
start | 坐标系 | 起始点 |
end | 坐标系 | 结束点 |
options? | 对象 | 可选参数(默认 {}) |
