eng.great-circle-bearing Calculator
Calculates the great circle bearing (initial course) between two geographic coordinates using spherical trigonometry. Great circle routes are the shortest path on a sphere — a flight from London to Los Angeles via great circle crosses Greenland rather than following latitude lines.
Inputs
Lat1 Deg
Reference formula or conversion factor shown for context.
Lon1 Deg

Results
initial bearing (°)
Sample size or count used in the calculation.
great circle distance (km)
The computed distance or separation.
great circle distance (nm)
