Package Exports

turf-destination

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (turf-destination) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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
