Calculate Distance between two location (GeoPoint)

public double CalculationByDistance(Location Start, Location End)
{
        double Radius = 6371;
        double lat1 = Start.getLatitude();
        double lat2 = End.getLatitude();
        double lon1 = Start.getLongitude();
        double lon2 = End.getLongitude();
        double dLat = Math.toRadians(lat2 - lat1);
        double dLon = Math.toRadians(lon2 - lon1);
        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 km = Radius * c;
        return km * 1000;

distance between two cities of India? Take the help of the city distance search engine. The search engine helps in finding the distance between major cities.
