How To: Add a field containing a count of overlapping features in another layer
Instructions provided include step-by-step instructions for adding a field containing a count of overlapping features in another layer. For example, with a map that has a polygon layer representing states and a point feature representing cities, use this to calculate how many cities each state contains.
- In the ArcMap Table of Contents, right-click on the layer to apply the count to, and select Joins and Relates > Joins.
- In the 'Join' dialog box, specify the 'Join data from another layer based on spatial location' option.
- Specify the location and name of the output feature.
- Click OK.
The output feature has a field named count that lists the number of overlapping or intersecting features.
