@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
