Geographic geometry: © OpenStreetMap contributors, ODbL 1.0.
https://www.openstreetmap.org/copyright
Derived from the archived city-data water/landscape/roads and skyline-wuxi OSM snapshots.
Input file hashes and display assumptions are recorded in sources.json.

Elevation: archived Mapzen Terrarium tiles on AWS, with USGS SRTM source data.
https://github.com/tilezen/joerd/blob/master/docs/attribution.md
Display datum: 3 metres. Heights are interpolated, not a survey; water level and embankments are illustrative.

Spectral wave simulation and random generator adapted from Island.

Island's ocean implementation in turn credits the MIT submerged-snell-ocean example
from scottstts/threejs-awesome-graphics-agent-skills. See ISLAND-CREDITS.md.
Lake parameters and scenery are illustrative; the original tropical island is not used as Wuxi geography.

Ground textures: Poly Haven, CC0 1.0, optimized KTX2 derivatives from Island:
Leafy Grass — Charlotte Baglioni — https://polyhaven.com/a/leafy_grass
Dirt Floor — eye-candy.xyz — https://polyhaven.com/a/dirt_floor
Dark Rock 02 — Amal Kumar — https://polyhaven.com/a/dark_rock_02
Full upstream asset credits: ISLAND-CREDITS.md.
Leaf clusters and normals: Poly Haven Island Tree 02, CC0, Rob Tuytel (scanning, processing)
and Rico Cilliers (cleanup, processing), composited into an atlas by Island.

The three procedural tree silhouettes illustrate planting; the atlas does not identify surveyed Wuxi species.
Basis Universal decoder redistributed from Island, Apache 2.0; see basis/LICENSE.txt.

Vegetation and lighting: procedural display assets, not surveyed trees or photogrammetry.

Traveller: Microsoft Rocketbox Male_Adult_01, Microsoft / Rocketbox Studios, MIT.

Converted, optimized and outfit repainted by Island; derivative GLB redistributed unchanged.
Animations: Quaternius Universal Animation Library 1 & 2 (Standard), CC0 1.0,
retargeted to Rocketbox by Island. Only idle / walk / jog / sprint are used here.

Skin/hair material, straw hat and pose/foot placement adapted from Island (MIT).
The stable hair cutout is used without Island's temporal AA pipeline.

Clock and camera-relative rain construction adapted from Island TimeOfDay.ts / Weather.ts, MIT.
The fixed seasonal sun path, moon, stars and weather are illustrative, not live observations.
Ambient audio: CC0 recordings redistributed from Island (not recorded in Wuxi):
waves.ogg — beach_waves.mp3 — 3bagbrew

wind.ogg — Strong Wind — florianreichelt

rain.ogg — Soft Rain in Forest Raindrops fall on leaves — Borgory
https://freesound.org/people/Borgory/sounds/678435/

Road width: explicit archived width retained; otherwise recorded lanes × 3.25 m + 1 m display estimate, before road-class fallback. Not surveyed.
Bridge slabs, piers and rails are illustrative structures on tagged bridge segments over source water. Dimensions and deck elevations are estimates.
