Minimum bounding geography but ignore spatial outliers?

cumminsd2 — Fri, 05 Apr 2024 18:51:19 GMT

I have a point layers of several hundred thousand students. The attribute table includes a field for their school.

I want to create a sort of minimum bounding polygon around all the students at each school, but I want to ignore outliers. I would like to draw a convex hull, around, say, the 90% most clustered students for each school.

Is this possible? There are over a thousand schools and I an trying to map their core catchment areas.

Aggregate Points (Cartography)—ArcGIS Pro | Documentation would be a start

There are other clustering options in the Spatial Statistics extension.
