I wrote a Python script that would get you part way there: http://forums.arcgis.com/threads/17809-polygon-in-polygon-analysis-count-if?p=56528&viewfull=1#post56528 The script basically does a recursive SelectByLocation (maybe specify 1 mile selction radius?). The FC then gets a CLUSTER_ID field (you can name it whatever you want) added and populated. So if there were three "clusters" of points that were > 1 mile appart (but the points in the cluster were all < 1 mile appart) you would end up with 3 different CLUSTER_ID values. Then all you need to do is add the X and Y coordinates to the table, run the Summary Statistics tool (using CLUSTER_ID as the case field, and getting the mean X and Y coordinate values). Build a new FC based on teh output of the summary stats table. Presto. Hi csny490 I've got a similar problem as it is mentioned here in this Thread and I think, your python script would solve it perfectly! unfortunately, it's not available anymore under the link you pasted here. Could you upload it again? Or could you sent it to me personally? Thanks a lot! rinadr
