Hi,

I ArcGIS Pro, I have a point feature class on which I would like to procduce Thiessen polygons. However, instead of the regular Thiessen polygon behaviour on a single point, I would like to group the 50 closest points to each other in the feature class and to produce the Thiessen polygons accordingly...

It is porbably a 2 step workflow but I cannot figure out how. I looked at the Thiessen, Sort (Spatial sort with PEANO algorythm), Near and Point Distance tools with no luck.

some suggestions

How Grouping Analysis works—ArcGIS Pro | Documentation 

Generate Subset Polygons—Help | Documentation  (used to select the points within)

But the Voronoi diagrams (aka, Thiessen polygons) would probably have to be create on the subsets

Thanks Dan. Will look at the Spatial Statistics when I will  have more time...

For the time being, I will use the techniques shown here:

https://community.esri.com/thread/195092-group-every-near-50-points-together 

I am just trying to split spatially a large point features class in group of 50 points and possibly derive Thiessen polygons for display... It does not have to be exact.
