Great-circle distance between two points. Enter the co-ordinates into the text boxes to try out the calculations. A variety of formats are accepted, principally: deg-min-sec suffixed with N/S/E/W (e.g. 40°44′55″N, 73 59 11W), or. signed decimal degrees without compass direction, where negative indicates west/south (e.g. 40.7486, -73.9864):
Natural questions are to seek the great circle distance between two specified points and true course at points along the route. The required spherical trigonometric formulae are greatly simplified if angles and distances are measured in the appropriate natural units, which are both radians!
Use Great Circle Mapper to calculate the distance and flight duration between all airports worldwide and draw the flight route on a map.

Does the Great Circle Mapper assume Earth is a sphere? How does the Great Circle Mapper calculate distances and paths? Why does the example in Ed Williams' Aviation Formulary calculate a different distance for LAX-JFK?
22 wrz 2024 · The Great Circle Mapper displays maps and computes distances along a geodesic path. It includes an extensive, searchable database of airports and other locations.
