How Region To Polygon Coverage (Coverage) works

Below is a region coverage REGIONCOV with one region subclass, GREEN. The subclass contains three regions; the first region consists of one polygon, the second region consists of one polygon, the third region overlaps the other two regions and is made up of two polygons. Region To Polygon Coverage creates a polygon coverage from the subclass and constructs a table listing the association between the polygons of the Output Coverage and the regions of the Input Coverage Input Subclass.
