transformRotate

Description

Rotates any geojson Feature or Geometry of a specified angle, around its centroid or a given pivot point.

Parameters

Name	Type	Description
geojson	GeoJSON	object to be rotated
angle	number	of rotation in decimal degrees, positive clockwise
options?	Object	Optional parameters (default {})
options.pivot?	Coord	point around which the rotation will be performed (default 'centroid')
options.mutate?	boolean	allows GeoJSON input to be mutated (significant performance increase if true) (default false)

Returns

GeoJSON the rotated GeoJSON feature

Examples

const poly = turf.polygon([
  [
    [0, 29],
    [3.5, 29],
    [2.5, 32],
    [0, 29],
  ],
]);
const options = { pivot: [0, 25] };
const rotatedPoly = turf.transformRotate(poly, 10, options);
