Webbsimplify — 面将平滑为简单的形状。 面拥有最少线段数,同时尽可能接近原始栅格像元边缘,这就是平滑的实现方式。这是默认设置。 no_simplify — 面的边将与输入栅格的像元边缘完全保持一致。 使用此选项将面要素类转换回栅格,将产生与原始栅格相同的栅格。 WebbPolygon —The raster will be converted to a polygon feature dataset. Simplify lines or polygons. Specifies whether lines or polygons will be simplified (smoothed). The smoothing is done in such a way that the line contains a minimum number of segments while remaining as close as possible to the original raster cell edges.

Returns a "simplified" version of the given geometry using the Douglas-Peucker algorithm. Will actually do something only with (multi)lines and (multi)polygons but you can safely call it with any kind of geometry. Since simplification occurs on a object-by-object basis you can also feed a GeometryCollection to this function.
