Destination

Takes a Point and calculates the location of a destination point given a distance in degrees, radians, miles, or kilometers and bearing in degrees.

Example

import json
from turfpy.measurement import destination
from geojson import Point, Feature

origin = Feature(geometry=Point([-75.343, 39.984]))
distance = 50
bearing = 90
options = {'units': 'mi'}
print(json.dumps(destination(origin,distance,bearing,options), indent=2, sort_keys=True))

{
  "geometry": {
    "coordinates": [
      -74.398588,
      39.980168
    ],
    "type": "Point"
  },
  "properties": {},
  "type": "Feature"
}
