transformTranslate

Description

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

Parameters

Name	Type	Description
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 (default {})
options.units?	string	in which distance will be express; miles, kilometers, degrees, or radians (default 'kilometers')
options.zTranslation?	number	length of the vertical motion, same unit of distance (default 0)
options.mutate?	boolean	allows GeoJSON input to be mutated (significant performance increase if true) (default false)

Returns

GeoJSON the translated GeoJSON object

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