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.
