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 Coord the reference point
points FeatureCollection<Point> against input point set
options Object Optional parameters (optional, default {})
- options.units Units the units of the numeric result. Supports all valid Turf Units. (optional, default 'kilometers')

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.nearestPoint(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

This module is part of the Turfjs project, an open source module collection dedicated to geographic algorithms. It is maintained in the Turfjs/turf repository, where you can create PRs and issues.

Installation

Install this single module individually:

$ npm install @turf/nearest-point

Or install the all-encompassing @turf/turf module that includes all modules as functions:

$ npm install @turf/turf
