Optional parameters include `maxError`, which sets the tolerated error during reprojection, and `proj`, the operation's projection. The method returns a new geometry. Example shows creating a `MultiPolygon` object, a `BBox` geometry, and combining them with a `union` call, the result then being printed and displayed on a map.\n"]]
