Wherein, R and Distance units are identical, if using 6371.004 kms as radius, then
Distance is exactly km for unit, if it is desired that with other unit, such as mile, it is also necessary to do unit conversion, 1 km=
0.621371192mile, if only making positive and negative processing to longitude, without making 90-Latitude to latitude (assuming that being all north half
Ball, the Southern Hemisphere only have Australia to have application value) processing, then formula will be:C=sin (LatA) * sin (LatB)+cos
(LatA)*cos(LatB)*cos(MLonA-MLonB)
