The go language calculates the distance between two longitude and latitude _golang

The example in this article describes how the go language calculates the distance between two longitude and latitude. Share to everyone for your reference. The implementation methods are as follows:

Copy Code code as follows:

Package Main

Import (
"FMT"
"Math"
)

Func Main () {
LAT1: = 29.490295
Lng1: = 106.486654

LAT2: = 29.615467
Lng2: = 106.581515
Fmt. Println (Earthdistance (LAT1, Lng1, LAT2, lng2))
}

Func earthdistance (LAT1, Lng1, LAT2, lng2 float64) float64 {
Radius: = 6371000//6378137
rad: = Math. pi/180.0

LAT1 = LAT1 * rad
lng1 = Lng1 * rad
LAT2 = Lat2 * rad
Lng2 = Lng2 * rad

Theta: = Lng2-lng1
Dist: = Math. Acos (Math. Sin (LAT1) * Math. Sin (LAT2) + math. Cos (LAT1) * Math. Cos (LAT2) * Math. Cos (theta))

Return dist * radius
}
