APPENDIX C: DISTANCE CONVERTER
Title: Distance Converter between two known Latitude & Longitude Positions on the Earth.
Convert latitude and longitude from degrees into radians using Radians = degrees * (PI/180)
dlon = lon2-lon1 dlat=lat2-lat1
a = (sin (dlat/2))^2+cos (lat1)*cos (lat2)*(sin (dlon/2))^2)
c = 2 * arc tan (sqrt (a) /sqrt (1-a))
d = R * c (answer in km)
R = Radius of the Earth. R varies with Latitude from 6336 km (3937 mi) to 6399 km (3976 mi). At 30 degrees latitude, R is approximately 6367 km (3957 mi).
