  (https://www.openstreetmap.org/copyright). On screen: "© OpenStreetMap contributors".
- `berlin2/` adds, from OpenStreetMap (© OpenStreetMap contributors, ODbL): the region's land use, forests, lakes and rivers, roads,
  railways, building footprints and heights along the flight path, and BER's and Tempelhof's runways, taxiways and aprons
  (`airports.json`, `airports.glb`). Fetched through the Overpass API (overpass-api.de and the overpass.kumi.systems mirror).
  The terrain is derived from that data; no terrain model is used.
- BER Terminal 1, its piers, Terminal 2 and the DFS tower (`landmarks.glb`) are procedural models fitted to OpenStreetMap footprints
  and heights (© OpenStreetMap contributors, ODbL). No logos or brand text.
