Demonstrates how to perform geometry-on-geometry spatial operations by using GeometryEngine. Two input Polygons are added as Graphics to a GraphicsOverlay and displayed in a MapView. Using the options menu, different spatial operations can be performed, the result of which is shown as a third Graphic, in red, in the MapView. Additionally, the union method is used to create an initial geometry with which to set the Viewpoint of the MapView.

The GeometryEngine methods difference, intersection, symmetricDifference, and union all perform geometry-on-geometry operations against two Geometry objects. The result is represented by a third Geometry that is returned from the method call.
// perform intersection
GeometryEngine.intersection(inputPolygon1, inputPolygon2)
// perform union
GeometryEngine.union(inputPolygon1, inputPolygon2)
