I have 19 polygon shapefile layers, with some occasionally overlapping with one another. As a final output, I would like a shapefile that includes only the overlapping areas between 2 or more of these 19 layers (and if it could keep their respective attributes, that would be fantastic).
The Intersect tool provides an ideal output, yet if I add all 19 layers as the inputs, it searches for areas where all 19 intersect. The only remedy I can currently imagine is doing pairwise intersections, which would mean I'd have to do it 171 times, then merge them all into one shapefile layer.
I cannot seem to find a method for what I want to do that doesn't involve painful pairwise analyses.
