    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 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> FeatureCollection containing the smoothed polygon/poylgons
