Transform Translate

Moves any geojson Feature or Geometry of a specified distance along a Rhumb Line on the provided direction angle.

Example

import json
from turfpy.transformation import transform_translate
from geojson import Polygon, Feature
f = Feature(geometry=Polygon([[[0,29],[3.5,29],[2.5,32],[0,29]]]))
tt = transform_translate(f, 100, direction=35, mutate=True)
print(json.dumps(tt, indent=2, sort_keys=True))

{
  "geometry": {
    "coordinates": [
      [
        [
          0.591903,
          29.73668
        ],
        [
          4.091903,
          29.73668
        ],
        [
          3.110728,
          32.73668
        ],
        [
          0.591903,
          29.73668
        ]
      ]
    ],

  },
  "properties": {},
  "type": "Feature"
}

Interactive Example

from ipyleaflet import Map, GeoJSON, LayersControl

original = GeoJSON(name='Original', data=f)

rotated = GeoJSON(name='Translated', data=transform_translate(f, 100, 35, mutate=True), style={'color': 'red'})

m = Map(center=[30.18519925274955, 2.939529418945313], zoom=5)

m.add_layer(original)
m.add_layer(rotated)

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