turf-voronoi-delaunay

voronoi

Takes a FeatureCollection of points, and a bounding box, and returns a FeatureCollection of Voronoi polygons.

The Voronoi algorithim used comes from the d3-delaunay package.

Parameters

• points FeatureCollection<Point> to find the Voronoi polygons around.

• options Options Optional parameters (optional, default {keepProperties:false,bbox:[-180,-85,180,85]})

  • options.keepProperties boolean switch to enable/disable preservation of feature properties (optional, default false)
  • options.bbox BBox clipping rectangle, in [minX, minY, maxX, MaxY] order. (optional, default [-180,-85,180,85])

Examples

const options = {
  bbox: [-70, 40, -60, 60]
};
const points = turf.randomPoint(100, options);
const voronoiPolygons = voronoiDelaunay(points, options);

//addToMap
const addToMap = [voronoiPolygons, points];

Returns FeatureCollection<Polygon> a set of polygons, one per input point.
