@spatial/bearing
bearing
Takes two points and finds the geographic bearing between them, i.e. the angle measured in degrees from the north line (0 degrees)
Parameters
-
start
Coord starting Point -
end
Coord ending Point -
options
Object Optional parameters (optional, default{}
)-
options.final
boolean calculates the final bearing if true (optional, defaultfalse
)

Examples
var point1 = turf.point([-75.343, 39.984]);
var point2 = turf.point([-75.534, 39.123]);
var bearing = turf.bearing(point1, point2);
//addToMap
var addToMap = [point1, point2]
point1.properties['marker-color'] = '#f00'
point2.properties['marker-color'] = '#0f0'
point1.properties.bearing = bearing
Returns number bearing in decimal degrees, between -180 and 180 degrees (positive clockwise)
