Models optimized for browser use; tree positions follow mapped OSM vegetation, while roadside rock and grass details are generated scenery. The HRTC-inspired bus and cabin are original generated geometry, not an official or scanned HRTC vehicle. Three.js loaders use the bundled Three.js MIT license.

- Mature broadleaf tree: https://polyhaven.com/a/island_tree_02 — CC0. Simplified from 1,072,213 to 22,879 triangles for browser rendering.
- Six textured civilian characters and compatible walk/idle/look clips: Microsoft Rocketbox, MIT, https://github.com/microsoft/Microsoft-Rocketbox . GLB distribution: https://models.codelove.in . Full notices retained in people/LICENSE.txt.
- Rendering/animation addons: Three.js r160, MIT (vendor/THREE-LICENSE.txt). Meshopt decoder from the r160 Three.js distribution, MIT.


Regional ambient animals: Microsoft Rocketbox cow-brown-01 and dog-germanshepard-01, MIT. Full copyright and license: animals/LICENSE.txt. Source: https://github.com/microsoft/Microsoft-Rocketbox ; compressed GLB distribution: https://models.codelove.in . Vehicles, train and light-plane geometry are original generated assets. Train motion and airport terminal layouts are simulated/inferred.

Maranda preview: broadleaf.png and maranda-grass/color.jpg are AI-generated texture assets, produced with OpenAI image generation. They texture 3D foliage and ground; they are not screenshots or a photographed reconstruction. Infill architecture and landscaping are inferred.

Land-cover reconstruction: © ESA WorldCover project 2021 / Contains modified Copernicus Sentinel data (2021) processed by ESA WorldCover consortium. CC BY 4.0. https://esa-worldcover.org/en/data-access . Raw class values, geographic window cropped/resampled for this game. Generated objects and inferred houses are not surveyed replicas.

Microsoft Global ML Building Footprints: satellite-derived geometry cropped from the 2026-07-24 India release, quadkey 123103322. Source URL and crop bounds in data/buildings/index.json. Data license: CDLA Permissive 2.0 (Microsoft's notice in data/buildings/LICENSE.txt; full agreement https://cdla.dev/permissive-2-0/). Geometry is detected, not surveyed. This crop has no height estimates; rendered heights and architecture are generated. Source project: https://github.com/microsoft/GlobalMLBuildingFootprints .


## Vehicle recordings

See [Vehicle sound credits](audio/CREDITS.md). Includes **Porter Prop plane Int.WAV by jakobthiesen, CC BY 3.0**, adapted into a loop. Other vehicle/gear recordings are CC0; full source links and modifications are listed there.

747-style jet: original procedural game model, not an official Boeing asset. Approximate dimensions referenced from Boeing 747-400 airport planning document: https://www.boeing.com/content/dam/boeing/boeingdotcom/commercial/airports/acaps/747-400_Rev_F.pdf . Flight handling remains an arcade approximation. Airport surfaces follow available OpenStreetMap geometry; unmapped terminal layouts use simplified scenery.

Regional bus game liveries are original approximations, not official replicas. Named operator references: HRTC https://hrtchp.com/hrtc_info/ , Haryana Roadways https://hartrans.gov.in/ , RSRTC https://transport.rajasthan.gov.in/content/transportportal/en/RSRTC/contact-us.html , DTC https://dtc.delhi.gov.in/ . Other state/UT options use generic state-inspired labels and colours.
