Examples
var searchWithin = turf.featureCollection([
turf.polygon([[
[-46.653,-23.543],
[-46.634,-23.5346],
[-46.613,-23.543],
[-46.614,-23.559],
[-46.631,-23.567],
[-46.653,-23.560],
[-46.653,-23.543]
]])
]);
var points = turf.featureCollection([
turf.point([-46.6318, -23.5523]),
turf.point([-46.6246, -23.5325]),
turf.point([-46.6062, -23.5513]),
turf.point([-46.663, -23.554]),
turf.point([-46.643, -23.557])
]);
var ptsWithin = turf.within(points, searchWithin);
//addToMap
var addToMap = [points, searchWithin, ptsWithin]
turf.featureEach(ptsWithin, function (currentFeature) {
currentFeature.properties['marker-size'] = 'large';
currentFeature.properties['marker-color'] = '#000';
});
Returns FeatureCollection<Point> points that land within at least one polygon
