ALT 3D map of Manhattan seen from the south-west at noon, with the Empire State Building marked in the middle. Buildings in sight from its 86th-floor terrace, 320 m up, are dark blue; buildings hidden behind other buildings are grey, estimated. Most of Midtown and Lower Manhattan near the tower is blue; the towers hide the ground behind them, and Central Park, at the top, is almost entirely grey. The Hudson River and New Jersey are on the left, the East River and Roosevelt Island on the right. A legend panel reads "What you see from the Empire State", with the date 2026-11-05 12:00 and the sources: NYC Open Data Building Footprints and OpenStreetMap.
