Feb 13, 2015 at 20:46 comment added Chris W You don't want Intersect if you're limited to just two inputs. Since it only returns areas common to both inputs, you'd have to intersect every layer with every other layer, then all of those intersect results with each other, and so on (some results will be null, and all results must be combined to count overlaps). You want Union, which keeps all areas of both inputs, but creates new shapes out of the areas of overlap (so it can 'build' on a previous result). Note that depending on how the shapes overlap, you could end up with an tremendous number of polygons that are just little slivers.
