Distance and Azimuth Between Two Points
Specify the latitudes and longitudes of two points on Earth to calculate the shortest distance and its azimuth, and indicate the direction from point A to B.
Please specify western longitude and southern latitude as negative values.
The default latitude and longitude values for the B location represent Mecca.
The default latitude and longitude values for the B location represent Mecca.
A to B azimuth
Calculations are based on the Earth as a sphere with an equatorial radius of r = 6378.137 km.
Azimuths are measured as North: 0 degrees, East: 90 degrees, South: 180 degrees, and West: 270 degrees.
Location A (longitude x1, latitude y1) and location B (longitude x2, latitude y2)
