@spatial/rhumb-bearing

rhumbBearing

Takes two points and finds the bearing angle between them along a Rhumb line i.e. the angle measured in degrees start the north line (0 degrees)

Parameters

• start Coord starting Point
• end Coord ending Point
• options Object? Optional parameters
  • options.final boolean calculates the final bearing if true (optional, default false)

Examples

var point1 = turf.point([-75.343, 39.984], {"marker-color": "#F00"});
var point2 = turf.point([-75.534, 39.123], {"marker-color": "#00F"});

var bearing = turf.rhumbBearing(point1, point2);

//addToMap
var addToMap = [point1, point2];
point1.properties.bearing = bearing;
point2.properties.bearing = bearing;

Returns number bearing from north in decimal degrees, between -180 and 180 degrees (positive clockwise)
