a donut polygon is a polygon with one or more holes in it. Such a feature is regarded as a complex geometry, having an outer ring of coordinates, and one or more inner rings of coordinates that represent the (donut) holes. An example of a donut polygon would be a lake with an island, the extent of the water in the lake is the polygon and the hole is the island.
