This operation supports GML coming from a WMS or WFS Service. . The spatial analysis methods (like buffer,intersect,union,difference,symDifference,convexHull) will return the most specific class possible to represent the result. If the result is homogeneous, a Point, LineString, or Polygon will be returned if the result contains a single element; otherwise, a MultiPoint, MultiLineString, or MultiPolygon will be returned. If the result is heterogeneous a GeometryCollection will be returned. For faster spatial analysis, use simplication (option available for all processs) either Douglas-Peucker or Topology Preserving algorithm. It will ensure that any polygonal geometries returned are valid BUT simple lines are not guaranteed to remain simple after simplification. Important note: Using Douglas-Peucker simplification does not preserve topology; e.g. polygons can be split, collapse to lines or disappear holes can be created or disappear, and lines can cross.
