Show HN: Dovepass – can I legally fly a drone along this exact path in SF?

Dovepass is a web tool that answers “Can I legally fly a drone along this exact path in San Francisco?” by combining route planning, aircraft specs, and regulatory checks. Enter a takeoff and destination, pick or add your drone (weight, battery Wh, speeds, payload, Remote ID, etc.), set time and cruise height, and the app shows a map with buildings, a side‑view height chart, numbered waypoints, and a single clear verdict plus step‑by‑step actions. Outputs include LAANC/airspace guidance, printable flight cards and files for DJI and other apps. Checks follow FAA Part 107: airspace and airport permission zones, daily temporary flight restrictions, stadium game rules, SF park and national park closures (Crissy Field, Ocean Beach, Alcatraz), Presidio, Golden Gate Bridge, jails, terrain/building clearance under 400 ft, wind/battery limits, and unaided visual‑line‑of‑sight constraints; Remote ID absence is a no‑go.

Data sources and limits are explicit: buildings from OpenStreetMap + DataSF LIDAR, terrain from USGS 3DEP, daily FAA mirrors (UAS Facility Map, Class airspace, stadiums) and TFRs, METAR and Open‑Meteo winds, and park rule mirrors. Live air traffic, localized weather along the route, private property permissions, privacy/filming permits, cranes/new construction and full Port of SF property are not checked. Dovepass is a research prototype and not a flight authorization; the pilot in command must confirm live rules and permissions with the FAA and land owners before flying.
