@turf/polygon-smooth

polygonSmooth

Smooths a Polygon or MultiPolygon. Based on Chaikin's algorithm. Warning: may create degenerate polygons.

Parameters

• inputPolys (FeatureCollection<(Polygon | MultiPolygon)> | Feature<(Polygon | MultiPolygon)> | Polygon | MultiPolygon) (Multi)Polygon(s) to smooth

• options Object Optional parameters (optional, default {})

  • options.iterations string The number of times to smooth the polygon. A higher value means a smoother polygon. (optional, default 1)

Examples

var polygon = turf.polygon([[[11, 0], [22, 4], [31, 0], [31, 11], [21, 15], [11, 11], [11, 0]]]);

var smoothed = turf.polygonSmooth(polygon, {iterations: 3})

//addToMap
var addToMap = [smoothed, polygon];

Returns FeatureCollection<(Polygon | MultiPolygon)> FeatureCollection containing the smoothed polygon/multipoylgons
