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
Feature<Point> the reference pointpoints
FeatureCollection<Point> against input point set
Examples
var point = "type": "Feature" "properties": "marker-color": "#0f0" "geometry": "type": "Point" "coordinates": 28965797 41010086 ;var against = "type": "FeatureCollection" "features": "type": "Feature" "properties": {} "geometry": "type": "Point" "coordinates": 28973865 41011122 "type": "Feature" "properties": {} "geometry": "type": "Point" "coordinates": 28948459 41024204 "type": "Feature" "properties": {} "geometry": "type": "Point" "coordinates": 28938674 41013324 ; var nearest = turf;nearestproperties'marker-color' = '#f00'; var resultFeatures = againstfeatures;var result = "type": "FeatureCollection" "features": resultFeatures; //=result
Returns Feature<Point> the closest point in the set to the reference point
