Hi all,

My question about is about the Collect Events Tool (Spatial Statistics). Here is the link [ATTACH=CONFIG]21455[/ATTACH]http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//005p0000003s000000

It is said that "this tool will only combine features that have the exact same X and Y centroid coordinates." My question is, is there any difference between X and Y centroid coordinates and X and Y coordinates? I'm asking because in the illustration pictures provided by Eris, you can see the output has one more dot than the input. At first, I though the Collect Events Tool was simply designed to calculate the number of overlapped points. But now it doubt it.

I have marked the extra point with a circle in the attachment.

Thanks a lot for the help.
