Anyone dialing grid size in ArcGIS Pro for near‑real‑time gun crime hotspots? I’ve been using 250 m hex bins with a 14‑day rolling window on NIBRS points, but patrol says the shapes feel too blobby. Worth shifting to a space‑time cube for clearer patterns, or stick with weighted KDE and tweak bandwidth?
I’ve had the same ‘14‑day rolling window’ issue — switching to a Space Time Cube with 8‑hour time steps and 200 m bins made the patterns less blobby and lined up with shifts in Pro. Just make sure you’ve got enough NIBRS volume per shift to keep the bins stable.
Blobby at 250 m/14 days usually means too much temporal smoothing — filter to the shift hours, cut to a 7‑day window, and run Optimized Hot Spot Analysis (Gi*, fixed 300 m band) instead of KDE for crisper clusters (Hot Spot Analysis (Getis-Ord Gi*) (Spatial Statistics)—ArcGIS Pro | Documentation). If counts per beat get too thin, nudge the band to 350 m or shrink to 200 m bins. Are you weighting NIBRS by offense severity or treating everything equal?
