Map tiles and generated building geometry use OpenStreetMap data:
Copyright OpenStreetMap contributors, available under the Open Database
License (ODbL). https://www.openstreetmap.org/copyright

Supplemental building footprints and mapped building attributes use Overture
Maps Foundation releases, distributed under ODbL 1.0. Individual upstream
dataset identifiers remain in SOURCE_TRACE.json; no per-feature license files
are emitted. https://docs.overturemaps.org/attribution/

The browser Overture reader bundles PMTiles 4.5.0, Mapbox Vector Tile JS 3.0.0,
Pbf 5.1.2, Point Geometry 1.1.0, and fflate 0.8.2. These are distributed under
their respective BSD-3-Clause, ISC, and MIT licenses. Package versions and the
complete dependency graph are pinned in package-lock.json.

The browser CityGML adapter bundles fast-xml-parser 5.11.2 under the MIT
license. Its version and transitive dependency graph are pinned in
package-lock.json.

The browser glTF adapter bundles the Google Draco glTF decoder 1.5.9 under
the Apache License 2.0. Its WebAssembly decoder is embedded in the generated
provider bundle so compressed municipal meshes remain browser-only.

Japanese textured LOD2 building meshes use Project PLATEAU open 3D city
models under CC BY 4.0. Provider and asset references remain in the single
EVIDENCE_MANIFEST.json. https://www.mlit.go.jp/plateau/site-policy/

The browser LAS/LAZ/COPC adapter bundles copc 0.0.9 under the MIT license and
laz-perf 0.0.7 under the Apache License 2.0. The locally shipped
dist/laz-perf.wasm is built by the laz-perf project. Package versions and the
transitive dependency graph are pinned in package-lock.json.

Terrain elevation uses Mapzen Terrain Tiles from the AWS Open Data program.
The dataset combines multiple open elevation sources with source-specific
attribution requirements. The complete attribution text embedded in generated
worlds is maintained at assets/terrain_attribution.txt.

  The distributed derivative removes studio/background planes and unused
  normal/occlusion/metallic-roughness maps. Runtime replaces baked stylized
  lighting textures with an inferred daylight material palette; shell geometry
  remains. Geographic placement, scale and appearance are inferred.
Detailed attribution and modifications are in
dist/assets/landmarks/ATTRIBUTION.txt and generated EVIDENCE_MANIFEST.json.
These artist reconstructions are not surveyed real-world geometry.
