使用R

Question

我想使用经度和纬度计算Excel文件中某些位置之间的距离，使用R软件，我以前从未尝试过这样做。如果有人可以帮助我，那将是非常好的。

非常感谢提前。

Answer 1

Try this to get distance in meters:

acos(sin(lat1)*sin(lat2) + cos(lat1)*cos(lat2)*cos(lon2-lon1)) * 6371000

Example : Distance between London (lat=52, lng=0) and Mumbai (lat=19, lng=72) is approx 8000 Kms

> acos( sin(19)*sin(52) + cos(19)*cos(52)*cos(72-0) ) * 6371000
[1] 8041318

Seems to be correct.
