Using a buffer to associate multiple features for each feature in a layer

AntoineNormandin — Mon, 28 Apr 2014 18:08:47 GMT

Hello,

I am trying to determine for each point in a layer which other points, in the same layer, are located within a certain distance.
I realize this is not particularly clear and have therefore attached an image of what I am trying to achieve.

As illustrated in the example, I have created a buffer around point 4502. Located within this buffer (B) are points 4500 and 4480. Therefore, the points 4500 and 4480 can be associated to 4502. Pursing with this logic, buffer A was created around point 4500 and overlaps 4498. Consequently, 4498 can be associated to 4500. This operation would have to be repeated for each point.

I then need to obtain an attribute table that would look like this:

Origin___Point 1___Point 2___....
4502____4500____4480
4500____4492
...

Thanks for your help!

How about ArcToolbox >> Analysis Tools>> Overlay >> Spatial Join
choose One to Many as the join operation, and set the search radius as desired. Then you need to create a crosstab to rearrange the data. Do this in excel (easiest as far as I am concerned) or try the Transpose Fields tool.
Best Regards,
