Roll Hill, August 2026

How this page is made

• Nothing that landed in the last 48 hours is counted, listed or drawn.
• Drawn paths are simplified to 10 m and lose their first and last 200 m; flights too short to keep an interior are counted but not drawn.
• The record's free-text description is never read into a page. Flights whose stated purpose names a domestic, sexual-assault, kidnapping, welfare, mental-health or juvenile matter are counted in totals and appear in neither the flight list nor on the map.
• Purposes are the agency's own words, grouped into classes by a committed lookup table; unmatched values are "Other" and blank ones "Not stated".
• Times are converted to the agency's clock through the IANA zone database, never a fixed offset.
• Boundary. "Roll Hill" is a neighborhood polygon from City of Cincinnati / CAGIS (Statistical Neighborhood Approximations 2020), licence recorded as "Public Domain", in the place layer file for Cincinnati.
• A flight counts for this area when its simplified path intersects the polygon (shapely). The join uses the unclipped line; only the clipped line is drawn.
