@turf/destination

destination

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.

Parameters

from Feature<Point> starting point
distance number distance from the starting point
bearing number ranging from -180 to 180
units [string] miles, kilometers, degrees, or radians (optional, default kilometers)

Examples

var point = {
  "type": "Feature",
  "properties": {
    "marker-color": "#0f0"
  },
  "geometry": {
    "type": "Point",
    "coordinates": [-75.343, 39.984]
  }
};
var distance = 50;
var bearing = 90;
var units = 'miles';

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

var result = {
  "type": "FeatureCollection",
  "features": [point, destination]
};

//=result

Returns Feature<Point> destination point
