如何计算两个GPS坐标之间的距离(使用纬度和经度)？

给定lat/long中的现有点,(以KM表示)和方位(以度数转换为弧度)的距离,我想计算新的纬度/经度.这个网站反复出现,但我无法让这个公式为我工作.

采用上述链接的公式为:

lat2 = asin(sin(lat1)*cos(d/R) + cos(lat1)*sin(d/R)*cos(?))

lon2 = lon1 + atan2(sin(?)*sin(d/R)*cos(lat1), cos(d/R)?sin(lat1)*sin(lat2))

上述公式适用于MSExcel,其中 -

asin          = arc sin()   
d             = distance (in any unit)   
R             = Radius of the earth (in the same unit as above)  
and hence d/r = is the angular distance (in radians)  
atan2(a,b)    = arc tan(b/a)  
? is the bearing (in radians, clockwise from north);  

这是我在Python中获得的代码.

import math

R = 6378.1 #Radius of the Earth
brng = 1.57 #Bearing is 90 degrees converted …
