Its two opposite reentrant corners and full orientation are retained in both LODs. No mapped building parts or height exist; original tags are preserved without fabricated survey values.","Alcatraz Federal Penitentiary Q1142661 identifies the prison; this model covers only the principal Cellhouse, Hospital and Administration envelope. Lighthouse, water tower, recreation yard, ruins and other island buildings are separate objects and excluded.","NPS https://www.nps.gov/places/000/alcatraz-cellhouse.htm establishes the1910–1912 reinforced-concrete building and three-story cellhouse. Facade rhythm, barred security glazing, cornice and roof-light positions are proportional interpretations from the individually inspected licensed Commons references, not measured elevations.","Authored body13.4m, parapet14.35m and roof-light ridge15.8m are approximate, inferred by comparing photographed bays with the mapped65×49m envelope. No surveyed height is claimed. Coarse terrain foundation skirts belong to the SDK; roof heights stay local to the model ground datum.","The inspected aerial predates solar installation. NPS https://www.nps.gov/articles/000/structural-upgrades-for-alcatraz-prison-hospital-wing.htm documents contemporary rooftop photovoltaics. The authored panel groups acknowledge that change; their positions, count and dimensions are inferred, rather than an exact1300-panel survey.","Thin grills and roof seams simplify in the low LOD. Security bars are real rods over wall-backed opaque window panels; all windows remain attached to the actual facade.
