Nearest Point

Takes a reference Point Feature and FeatureCollection of point features and returns the point from the FeatureCollection closest to the reference Point Feature.

Example

import json
from turfpy.measurement import nearest_point
from geojson import Point, Feature, FeatureCollection
f1 = Feature(geometry=Point([28.96991729736328,41.01190001748873]))
f2 = Feature(geometry=Point([28.948459, 41.024204]))
f3 = Feature(geometry=Point([28.938674, 41.013324]))
fc = FeatureCollection([f1, f2 ,f3])
t = Feature(geometry=Point([28.973865, 41.011122]))
print(json.dumps(nearest_point(t ,fc), indent=2, sort_keys=True))
