@turf/nearest-point

nearestPoint

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 string the units of the numeric result (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
