This calculator computes the great circle distance between two points on the earth's surface. The program is operated by entering two geographic points and then pressing the Calculate button. The entry form allows you to enter geographic position in degrees, minutes, and seconds.
This uses the ‘haversine’ formula to calculate the great-circle distance between two points – that is, the shortest distance over the earth’s surface – giving an ‘as-the-crow-flies’ distance between the points (ignoring any hills they fly over, of course!).
The shorter segment between two points on a great circle is the shortest path between the two points on the sphere, also known as an orthodrome or the great circle distance. You may calculate the great circle distance between two points on the Earth from the geographical coordinates.
