Dear GIS-users,

I am working for a forest service and one of our tasks is to do the administration of applications for logging concessions. I made a polygon feature within a geodatabase with the applications. It happens sometimes that several persons apply on the same area. To provide a better service to the clients I would like to create a map where you can see the number of overlapping applications for the whole country. I was checking with the geoprocessing tools, how you can count overlapping items within one feature but I didn't get any wiser of this. Can anyone help me with this issue. Thank you very much

You might run a spatial join of your polygons to the applications as points.  Check out your options but one of them is a count field showing how many points fall within it.

You might instead run an overlay of the points with the polygons and then dump the results into a pivot table for analysis or do an attribute join to get the results added back to the polygons and then analyze those results.
