turf-destination

turf destination module

turf.destination(start, distance, bearing, units)

Takes a Point feature and calculates the location of a destination point given a distance in degrees, radians, miles, or kilometers; and bearing in degrees. This uses the Haversine formula to account for global curvature.

Parameters

parameter	type	description
start	Point	a Point feature at the starting point
distance	Number	distance from the starting point
bearing	Number	ranging from -180 to 180
units	String	miles, kilometers, degrees, or radians

Example

var point1 = turf.point([-75.343, 39.984]);
var distance = 50;
var bearing = 90;
var units = 'miles';

var destination = turf.destination(point1, distance, bearing, units);
point1.properties['marker-color'] = '#0f0';
destination.properties['marker-color'] = '#f00';

var result = turf.featurecollection([point1, destination]);

//=result

Returns Point, a Point feature at the destination
