Intersect supports the following geometry types:
Intersect: line/line
Intersect: line/polygon
Intersect: point/polygon
Intersect: polygon/polygon
Union
Union determines the geometry that exists in either the Source or Overlay
geometry. Where the geometry intersects, additional features are created. The
resulting layer is the sum of the two comparison layers. Use Union to combine
two related polygon features. For example, create a new feature source that
combines the business district and the theater district when these two areas
overlap.
The resulting layer has the attributes of both the Source and Overlay features.
Union supports polygon/polygon comparisons only.
