Φ is latitude, λ is longitude, R is earth’s radius (mean radius = 6,371km) Points – that is, the shortest distance over the earth’s surface – giving an ‘as-the-crow-flies’ĭistance between the points (ignoring any hills they fly over, of course!). This uses the ‘ haversine’ formula to calculate the great-circle distance between two signed decimal degrees without compass direction, where negative indicates.deg-min-sec suffixed with N/S/E/W (e.g.Great-circle distance between two pointsĮnter the co-ordinates into the text boxes to try out the calculations.
