add 10 nearest random points around a target point to its attribute table

BRott — Sun, 11 Apr 2021 11:31:24 GMT

Hello,

for a statistical analysis I want to associate the 10 closest random points around my target points (cities) to the target points attribute table. I want to do this for multiple cities to afterwards get a mean distance of the city and its associated points to a target feature.

this is what I'd like the attribute table to look like. (excel just for visualisation). Has anyone made any experiences with this?

The closest you can get is Generate Near Table (Analysis)—ArcGIS Pro | Documentation

but usually for such an arrangement one uses scipy's cdist

scipy.spatial.distance.cdist — SciPy v1.6.2 Reference Guide

or one of my old posts using numpy's einsum

Generate Near Table for points - Esri Community

Are you generating these random points yourself as part of this workflow, or do the random points already exist as a data set?
