The equation above is incorrrect. -------- The above equation should read for the Great Circle Distance between Points A and B located as; A at location (Lat_A, Lon_A) and B at (Lat_B, Lon_B) Distance A to B = 60*ArcCos[Sin(Lat_A)*Sin(Lat_B) + Cos(Lat_A)*Cos(Lat_B) * Cos(Lon_A -Lon_B)] The result is in nautical miles. -------- Regards, |"""""| ( @ @ ) -oooO----(_)----Oooo- caseynf@XXX.XXX
