calculate_initial_compass_bearing

calculate_initial_compass_bearing(pointA, pointB)[source]

Calculates the bearing between two points.

The formulae used is the following:
θ = atan2(sin(Δlong).cos(lat2),

cos(lat1).sin(lat2) − sin(lat1).cos(lat2).cos(Δlong))

Parameters:

  • pointA – The tuple representing the latitude/longitude for the first point. Latitude and longitude must be in decimal degrees

  • pointB – The tuple representing the latitude/longitude for the second point. Latitude and longitude must be in decimal degrees

Returns:

The bearing in degrees

Returns Type:

float
