函数: destination()

destination<P>(origin: Coord, distance: number, bearing: number, options?: { units?: Units; properties?: P; }): Feature<Point, P>

Function

Takes a Point 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.

示例

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

var destination = turf.destination(point, distance, bearing, options);

//addToMap
var addToMap = [point, destination]
destination.properties['marker-color'] = '#f00';
point.properties['marker-color'] = '#0f0';
