Method Detail

distanceBetweenInMiles

public static double distanceBetweenInMiles(GeoCoordinate c1,
                                            GeoCoordinate c2)

Calculate the distance Between Geo Coordinates points in miles using spherical law of cosines formula. http://mathworld.wolfram.com/SphericalTrigonometry.html

Returns:

distance between c1 and c2 in miles.

distanceBetweenInKm

public static double distanceBetweenInKm(GeoCoordinate c1,
                                         GeoCoordinate c2)

Calculate the distance Between Geo Coordinates points in kilometers using spherical law of cosines formula. http://mathworld.wolfram.com/SphericalTrigonometry.html

Returns:

distance between c1 and c2 in kilometers.

haversineDistanceBetweenInKm

public static double haversineDistanceBetweenInKm(GeoCoordinate c1,
                                                  GeoCoordinate c2)

Calculate the distance Between Geo Coordinates points in kilimeters using Haversine formula. Supposedly this formula has better precisions (need further investigations). However, it's a much slower function that the spherical law of cosines formula.
