Android Distance Calculate distanceBetweenTwoPoints(double lat1, double lng1, double lat2, double lng2)

Description

distance Between Two Points

Declaration

public static double distanceBetweenTwoPoints(double lat1, double lng1,
            double lat2, double lng2) 

Method Source Code

//package com.java2s;

public class Main {
    public static double distanceBetweenTwoPoints(double lat1, double lng1,
            double lat2, double lng2) {
        int r = 6371; // average radius of the earth in km
        double dLat = Math.toRadians(lat2 - lat1);
        double dLon = Math.toRadians(lng2 - lng1);
        double a = Math.sin(dLat / 2) * Math.sin(dLat / 2)
                + Math.cos(Math.toRadians(lat1))
                * Math.cos(Math.toRadians(lat2)) * Math.sin(dLon / 2)
                * Math.sin(dLon / 2);
        double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));
        double d = r * c;
        return d;
    }/*from w  w w. ja va2 s .  c  o m*/
