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))

{
  "geometry": {
    "coordinates": [
      -97.512507,
      35.466172
    ],
    "type": "Point"
  },
  "properties": {},
  "type": "Feature"
}
