Calculation Information

The Haversine formula calculates the shortest distance between two points on Earth's surface:

a = sin^2(delta-phi/2) + cos(phi1) * cos(phi2) * sin^2(delta-lambda/2)
c = 2 * atan2(sqrt(a), sqrt(1-a))
d = R * c

Where: phi is latitude, lambda is longitude, R is Earth's radius (6,371 km)

Forward bearing from point A to point B:

theta = atan2(sin(delta-lambda) * cos(phi2), cos(phi1) * sin(phi2) - sin(phi1) * cos(phi2) * cos(delta-lambda))

Result is normalized to 0-360 degree range (true bearing)

Midpoint between two coordinates:

Bx = cos(phi2) * cos(delta-lambda)
By = cos(phi2) * sin(delta-lambda)
phi-m = atan2(sin(phi1) + sin(phi2), sqrt((cos(phi1) + Bx)^2 + By^2))
lambda-m = lambda1 + atan2(By, cos(phi1) + Bx)

Usage Guide & Applications

Single Route Calculation

Enter latitude and longitude coordinates for start and end points to calculate the great circle distance and bearing between two locations.
