Point In Polygon

Takes a Point or a Point Feature and Polygon or Polygon Feature as input and returns True if Point is in given Feature.

Example

from turfpy.measurement import boolean_point_in_polygon from geojson import Point, MultiPolygon, Feature point = Feature(geometry=Point([-77, 44])) polygon = Feature(geometry=MultiPolygon([([(-81, 41), (-81, 47), (-72, 47), (-72, 41), (-81, 41)],), ([(3.78, 9.28), (-130.91, 1.52), (35.12, 72.234), (3.78, 9.28)],)])) boolean_point_in_polygon(point, polygon)

Interactive Example

from turfpy.measurement import boolean_point_in_polygon from geojson import Point, MultiPolygon, Feature from ipyleaflet import Map, GeoJSON, LayersControl

point = Feature(geometry=Point([-77, 44])) polygon = Feature( geometry=MultiPolygon( [ ([(-81, 41), (-81, 47), (-72, 47), (-72, 41), (-81, 41)],), ([(3.78, 9.28), (-130.91, 1.52), (35.12, 72.234), (3.78, 9.28)],), ] ) ) boolean_point_in_polygon(point, polygon)

m = Map(center=[46.57868671298067, -40.91583251953126], zoom=2)

geo_json = GeoJSON(name="MultiPolygon Feature", data=polygon)

m.add_layer(geo_json)

point_geojson = GeoJSON(name="Point in Polygon", data=point)

m.add_layer(point_geojson)

control = LayersControl(position="topright") m.add_control(control)
