Hello, I have a polygon layer that contains overlapping areas. I would like to remove the overlapping areas based on a comparison of the overlapping attribute fields. In this example, keep only the area with the most recent year. I know I can do this by setting a topology rule and editing each overlap individually, but I'm trying to wrap my head around a faster way using the overlay toolset. Thanks for any help!

Hi Hailey,

Overlay tools (Union, Intersect etc.) can be run with a single input to find self-overlaps, which may very well help out with what you're trying to do!

I imagine in this case you would want to use Intersect! Worth running it and seeing what the output looks like.

Thanks for the tip Joshua! The resulting Intersect allowed me to process the overlaps pretty quickly.
