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

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

Installation

$ npm install turf-destination
