Method Description
CalcDistance ( Location sourceLocation, Location targetLocation ) : double

The Haversine formula according to Dr. Math. http://mathforum.org/library/drmath/view/51879.html dlon = lon2 - lon1 dlat = lat2 - lat1 a = (sin(dlat/2))^2 + cos(lat1) * cos(lat2) * (sin(dlon/2))^2 c = 2 * atan2(sqrt(a), sqrt(1-a)) d = R * c Where * dlon is the change in longitude * dlat is the change in latitude * c is the great circle distance in Radians. * R is the radius of a spherical Earth. * The locations of the two points in spherical coordinates (longitude and latitude) are lon1,lat1 and lon2, lat2.
