It alsocalculates the surface distance between them (in miles and kilometres).The shortest distance between 2 points follows the line of a “Great Circle” and thebearing is constantly changing throughout the journey.DiagramLat2 Long2End BearingDistanceStart BearingLat1, Long11, Long 1InputCo-ordinates of 2 known points:(Latitude1, Longitude1) & (Latitude2, Longitude2)Note: Geographical positions are given relative to the Greenwich meridian and Equator.OutputStart & Finish bearings:Distance:Start, EndMiles & KilometresPage 17 of 47
