C#中的纬度/经度点之间的方向

我有两个坐标在Lat Long格式.

如何从A点(例如纽约37.149472,-95.509544)确定以B为单位的方向(例如Toronto 40.714269,-74.005973)

我正在寻找一个值,如“340度”

在C#

解决方法 如果你想要一贯的轴承跟随你不想要最短的(大圆)路径,你想要一条Rhumb线

转换可移动类型脚本

static double DegreeBearing( double lat1,double lon1,double lat2,double lon2){ var dLon = ToRad(lon2-lon1); var dPhi = Math.Log( Math.Tan(ToRad(lat2)/2+Math.PI/4)/Math.Tan(ToRad(lat1)/2+Math.PI/4)); if (Math.Abs(dLon) > Math.PI) dLon = dLon > 0 ? -(2*Math.PI-dLon) : (2*Math.PI+dLon); return ToBearing(Math.atan2(dLon,dPhi));}public static double ToRad(double degrees){ return degrees * (Math.PI / 180);}public static double Todegrees(double radians){ return radians * 180 / Math.PI;}public static double ToBearing(double radians) { // convert radians to degrees (as bearing: 0…360) return (Todegrees(radians) +360) % 360;}// verify against the website exampleDegreeBearing(50.36389,-4.15694,42.35111,-71.04083);
