I have a polygon feature class in which the polygons frequently overlap each other. I want to find all of the unique combinations of overlapping polygons within that feature class. I believe I want to perform a Union on the feature class, but I also want to be able to concatenate the names so that each polygon has a unique name made up of the concatenated name of all the polygons that make it up. Any ideas on how to do this?
I figured it out. Do the union and then do a spatial join back to the original feature class and in the field map of the Spatial Join tool make the merge rule "Join" for whichever attribute you want to concatenate.
