## destination
|
|
|
|
Takes a [Point][1] 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][2] to account for global curvature.
|
|
|
|
**Parameters**
|
|
|
|
- `origin` **[Coord][3]** starting point
|
|
- `distance` **[number][4]** distance from the origin point
|
|
- `bearing` **[number][4]** ranging from -180 to 180
|
|
- `options` **[Object][5]** Optional parameters (optional, default `{}`)
|
|
- `options.units` **[string][6]** miles, kilometers, degrees, or radians (optional, default `'kilometers'`)
|
|
- `options.properties` **[Object][5]** Translate properties to Point (optional, default `{}`)
|
|
|
|
**Examples**
|
|
|
|
```javascript
|
|
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';
|
|
```
|
|
|
|
Returns **[Feature][7]<[Point][8]>** destination point
