    @turf/transform-rotate

    transformRotate

    Rotates any geojson Feature or Geometry of a specified angle, around its centroid or a given pivot point; all rotations follow the right-hand rule: https://en.wikipedia.org/wiki/Right-hand_rule

    Parameters

    • geojson GeoJSON object to be rotated
    • angle number of rotation (along the vertical axis), from North in decimal degrees, negative clockwise
    • options Object Optional parameters (optional, default {})
      • options.pivot Coord point around which the rotation will be performed (optional, default 'centroid')
      • options.mutate boolean allows GeoJSON input to be mutated (significant performance increase if true) (optional, default false)

    Examples

    var poly = turf.polygon([[[0,29],[3.5,29],[2.5,32],[0,29]]]);
    var options = {pivot: [0, 25]};
    var rotatedPoly = turf.transformRotate(poly, 10, options);
    
    //addToMap
    var addToMap = [poly, rotatedPoly];
    rotatedPoly.properties = {stroke: '#F00', 'stroke-width': 4};

    Returns GeoJSON the rotated GeoJSON feature
