Envelop

Takes any number of features and returns a rectangular Polygon that encompasses all vertices.

Example

import json
from turfpy.measurement import envelope
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(envelope(feature_collection), indent=2, sort_keys=True))
