Advanced Interactive Geodesic Bearing Calculator
How to Use:
- Enter Coordinates: Input the Latitude and Longitude (in decimal degrees) for Point 1 (Origin) and Point 2 (Destination).
- Latitude values: -90 to +90 degrees (positive for North, negative for South).
- Longitude values: -180 to +180 degrees (positive for East, negative for West).
- Calculate: Click the "Calculate Bearings" button.
- View Results: The calculator will display:
- Initial Bearing: The direction from Point 1 towards Point 2 (0-360° clockwise from North).
- Final Bearing: The direction from Point 2 back towards Point 1 (0-360° clockwise from North).
- Distance: The great-circle distance between the points (using Haversine for simplicity here, though a true geodesic formula is more complex for bearings).
- Copy & Log: Use the "Copy" buttons for individual results and review the Action Log for calculation details.
This calculator uses formulas suitable for an ellipsoidal Earth model (WGS-84) for bearing calculations. The distance shown is based on the Haversine formula for a sphere, which is a good approximation for most purposes. True geodesic distances on an ellipsoid are more complex to calculate.
