函数: polygonSmooth()

polygonSmooth(inputPolys: Polygon | MultiPolygon | Feature<Polygon | MultiPolygon, GeoJsonProperties> | FeatureCollection<Polygon | MultiPolygon, GeoJsonProperties>, options?: { iterations?: number; }): FeatureCollection<Polygon | MultiPolygon>

Function

Smooths a Polygon or MultiPolygon. Based on Chaikin's algorithm

. Warning: may create degenerate polygons.

参数

inputPolys

(Multi)Polygon(s) to smooth

Polygon | MultiPolygon | Feature<Polygon | MultiPolygon, GeoJsonProperties> | FeatureCollection<Polygon | MultiPolygon, GeoJsonProperties>

options?

Optional parameters

iterations?

number

The number of times to smooth the polygon. A higher value means a smoother polygon.

返回

FeatureCollection<Polygon | MultiPolygon>

FeatureCollection containing the smoothed polygon/multipoylgons

示例

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];
