Readme
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 rotatedangle number of rotation (along the vertical axis), from North in decimal degrees, negative clockwiseoptions Object Optional parameters (optional, default {})
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
