Map landmark and event-coordinate audit — October 1, 2026

The map’s site precision promises that a coordinate marks the place itself. This pass rechecked selected pins whose existing notes already distinguish a reference point from the event or structure.

Changes

  • Flight 977 at Cape May County Airport: the point is the airport reference, while the NTSB location described in the existing pin note is roughly 4,000 feet short of runway 19. Changed to locality.
  • Atlantus: the GNIS point is Sunset Beach, a viewing location; the hull is offshore. Changed to locality.
  • Four Lakehurst entries (1944 radar, Hindenburg, 1932 aircraft-carrier trials, 1927 Los Angeles mooring): all use one GNIS coordinate for Naval Air Station Lakehurst. It identifies the station, not a surveyed radar apparatus, mooring mast or flight track. Changed to locality. The prior correction away from the borough of Lakehurst remains valid.
  • Morro Castle: the point is Convention Hall, a landmark beside the grounded hull, not a surveyed grounding coordinate. Changed to locality. Asbury Park Historical Society confirms the hull beached near the hall and the memorial is just south of it.
  • Weymouth Furnace entry and place: the two points differ by about 180 m, and the entry concerns a ruin complex with structures from more than one industry. Neither pin identifies an individual foundation. Changed to locality.
  • Aetna Furnace place: the location was sourced to a community-map pin; the cited road reference is about 330 m away and cannot independently establish a furnace footprint. Changed to locality.
  • Bear Swamp Hill place: the GNIS point identifies a hill near a 2024 search, not the spot where the person’s vehicle was found. Changed to locality.
  • Barnegat Lighthouse: retained as site precision but moved the story pin from a park-level point about 120 m away to the mapped lighthouse structure (39.76434, -74.10624). This agrees with the OpenStreetMap lighthouse feature already noted in the record and the Bureau of Ocean Energy Management viewpoint map, which gives virtually the same coordinates. The NJ state park page confirms the named structure and park setting.

Limits

These are precision corrections to the archive’s existing coordinates, not a full resurvey. They avoid turning a named airport, beach, station or building used as a reference into a claim about an exact historical event point. Other site pins remain for individual review.
