Center

Takes a Feature or FeatureCollection and returns the absolute center point of all features.

Example

import json from turfpy.measurement import center from geojson import Feature, FeatureCollection, Point

f1 = Feature(geometry=Point((-97.522259, 35.4691))) f2 = Feature(geometry=Point((-97.502754, 35.463455))) f3 = Feature(geometry=Point((-97.508269, 35.463245))) feature_collection = FeatureCollection([f1, f2, f3]) print(json.dumps(center(feature_collection), indent=2, sort_keys=True))

Interactive Example

from turfpy.measurement import center from geojson import Feature, FeatureCollection, Point from ipyleaflet import Map, GeoJSON, WidgetControl, LayersControl, CircleMarker

f1 = Feature(geometry=Point((-97.522259, 35.4691))) f2 = Feature(geometry=Point((-97.502754, 35.463455))) f3 = Feature(geometry=Point((-97.508269, 35.463245))) feature_collection = FeatureCollection([f1, f2, f3])

m = Map(center=[35.467146770097315, -97.50865470618012], zoom=15)

geo_json = GeoJSON(name="Geojson", data=feature_collection)

centre_coord = center(feature_collection)["geometry"]["coordinates"] circle_marker = CircleMarker(name="Center") circle_marker.location = (centre_coord[1], centre_coord[0]) circle_marker.radius = 30 circle_marker.color = "red"

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

m.add_layer(geo_json) m.add_layer(circle_marker) m
