Python calculates distances based on latitude and longitude examples

Copy the Code code as follows:

/**
* Calculate distance between two points
* @param _lat1-start Latitude
* @param _lon1-start Longitude
* @param _lat2-end Latitude
* @param _lon2-end Longitude
* @return km (rounded)
*/
public static double Getdistance (double _lat1,double _lon1, double _lat2,double _lon2) {
Double LAT1 = (math.pi/180) *_lat1;
Double lat2 = (math.pi/180) *_lat2;

Double lon1 = (math.pi/180) *_lon1;
Double lon2 = (math.pi/180) *_lon2;

Earth radius
Double R = 6378.1;

Double d = Math.acos (Math.sin (LAT1) *math.sin (LAT2) +math.cos (LAT1) *math.cos (LAT2) *math.cos (lon2-lon1)) *r;

return new BigDecimal (d). Setscale (4,BIGDECIMAL.ROUND_HALF_UP). Doublevalue ();
}

public static void Main (string[] args) {
System.out.println (Getdistance (45.73990, 126.55893, 45.73876, 126.55037));
}
