Package Exports

@turf/nearest

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/nearest) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@turf/nearest

nearest

Takes a reference point and a FeatureCollection of Features with Point geometries and returns the point from the FeatureCollection closest to the reference. This calculation is geodesic.

Parameters

targetPoint (Geometry | Feature<Point> | Array<number>) the reference point
points FeatureCollection<Point> against input point set

Examples

var targetPoint = turf.point([28.965797, 41.010086], {"marker-color": "#0F0"});
var points = turf.featureCollection([
    turf.point([28.973865, 41.011122]),
    turf.point([28.948459, 41.024204]),
    turf.point([28.938674, 41.013324])
]);

var nearest = turf.nearest(targetPoint, points);

//addToMap
var addToMap = [targetPoint, points, nearest];
nearest.properties['marker-color'] = '#F00';

Returns Feature<Point> the closest point in the set to the reference point
