函数: pointsWithinPolygon()

pointsWithinPolygon<G, P>(points: Feature<Point | MultiPoint, P> | FeatureCollection<Point | MultiPoint, P>, polygons: G | Feature<G, GeoJsonProperties> | FeatureCollection<G, GeoJsonProperties>): FeatureCollection<Point | MultiPoint, P>

Function

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

类型参数

G

G extends Polygon | MultiPolygon

P

P extends GeoJsonProperties

参数

points

Point(s) or MultiPoint(s) as input search

Feature<Point | MultiPoint, P> | FeatureCollection<Point | MultiPoint, P>

polygons

(Multi)Polygon(s) to check if points are within

G | Feature<G, GeoJsonProperties> | FeatureCollection<G, GeoJsonProperties>

返回

FeatureCollection<Point | MultiPoint, P>

Point(s) or MultiPoint(s) with positions that land within at least one polygon. The geometry type will match what was passsed in
