@turf/points-within-polygon

pointsWithinPolygon

Finds Points or MultiPoint coordinate positions that fall within (Multi)Polygon(s).

Parameters

• points (Feature | FeatureCollection<(Point | MultiPoint)>) Point(s) or MultiPoint(s) as input search
• polygons (FeatureCollection | Geometry | Feature<(Polygon | MultiPolygon)>) (Multi)Polygon(s) to check if points are within

Examples

var points = turf.points([
    [-46.6318, -23.5523],
    [-46.6246, -23.5325],
    [-46.6062, -23.5513],
    [-46.663, -23.554],
    [-46.643, -23.557]
]);

var searchWithin = 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 ptsWithin = turf.pointsWithinPolygon(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 | MultiPoint)> Point(s) or MultiPoint(s) with positions that land within at least one polygon. The geometry type will match what was passsed in
