I have a series of buffers representing service areas of bike share stations that extend 400 from the station (network distance). The polygons were generated using Network Analyst. Evidently, buffers of stations that are close to each other overlap. My question is how do I calculate the overlap when the polygons are in the same shapefile (they are rows of an attribute table) and not two different layers?
I tried using the tool 'Polygon Neighbos' but it generated an empty table.
Any thoughts about how I could proceed?
