Hempstead Police Department

How this page is made

• Every flight in the agency's published record is counted and listed; drawn paths are the whole flight, takeoff to landing.
• The record's free-text description is never read into a page. A flight whose stated purpose names a domestic, sexual-assault, kidnapping, welfare, mental-health or juvenile matter is listed like any other but drawn as a generalised area, not a path.
• Operators are the agency's own accounts in the record, numbered within the agency in order of first flight; no name or address is read into a page.
• Purposes are the agency's own words, grouped into classes by a fixed list of terms; unmatched values are "Other" and blank ones "Not stated".
• Times are shown on the agency's own local clock.
• Without filters the map draws at most 400 flights, sampled evenly from the latest full month, and the flight list is that month, capped at 500 rows. With filters the map draws at most 400 and the list at most 500, both sampled evenly, and the count line says when a cap applied. The whole-record option is an even 400-flight sample.
