turf transform-translate module

Usage no npm install needed!

<script type="module">
  import turfTransformTranslate from 'https://cdn.skypack.dev/@turf/transform-translate';




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


  • geojson GeoJSON object to be translated
  • distance number length of the motion; negative values determine motion in opposite direction
  • direction number of the motion; angle from North in decimal degrees, positive clockwise
  • options Object Optional parameters (optional, default {})
    • options.units string in which distance will be express; miles, kilometers, degrees, or radians (optional, default 'kilometers')
    • options.zTranslation number length of the vertical motion, same unit of distance (optional, default 0)
    • options.mutate boolean allows GeoJSON input to be mutated (significant performance increase if true) (optional, default false)


var poly = turf.polygon([[[0,29],[3.5,29],[2.5,32],[0,29]]]);
var translatedPoly = turf.transformTranslate(poly, 100, 35);

var addToMap = [poly, translatedPoly];
translatedPoly.properties = {stroke: '#F00', 'stroke-width': 4};

Returns GeoJSON the translated GeoJSON object
