polygonSmooth
Smooths a Polygon or MultiPolygon. Based on Chaikin's algorithm. Warning: may create degenerate polygons.
Parameters
inputPolys
(FeatureCollection | Feature<(Polygon | MultiPolygon)>) (Multi)Polygon(s) to smoothoptions
Object Optional parameters (optional, default{}
)options.iterations
string THe number of times to smooth the polygon. A higher value means a smoother polygon. (optional, default1
)
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> FeatureCollection containing the smoothed polygon/poylgons
