Copyright © 2026 9570-6198 Québec inc. (Codriver) and contributors.
Individual model manifests and catalog entries retain their creators’ copyright and credit.

The original procedural code, viewer, build tools and documentation in this
repository are released under the [MIT License](LICENSE).

The original 3D models under `public/models/` are released under
[Creative Commons Attribution 4.0 International](https://creativecommons.org/licenses/by/4.0/)
(CC BY 4.0). You may share, modify and use them commercially under that license.
Keep appropriate credit, link the license, and indicate your changes.

Credit the creator(s) listed in each model manifest. For the original Codriver collection, suggested credit is:

Geographic data derived from OpenStreetMap remains under ODbL 1.0. MIT and
CC BY do not relicense third-party data. The extracted alignments, footprints
and site coordinates are available in the source repository; preserve their
attribution and comply with the ODbL when redistributing the data or a derivative
database. See [THIRD_PARTY_NOTICES.md](THIRD_PARTY_NOTICES.md).

## Additional permission for Codriver products

Outside contributors expressly accepting the [Contributor License Agreement](CONTRIBUTOR-LICENSE.md) grant Codriver separate commercial and sublicensing rights without individual contributor attribution in its apps, products or marketing. They retain ownership and receive recognition in the public 3D asset library. This permission applies only to identified contributions and rights covered by an accepted grant; see the [acceptance procedure](docs/contribution-acceptance.md).

The agreement does not rewrite MIT or CC BY, waive a third party’s rights, or apply retroactively. People using public models under CC BY still provide that license’s attribution. Codriver must separately comply with OSM and other third-party terms; the agreement removes no notices or credits owed to those parties.

Reference links identify material studied while modeling. Photographs, plans,
simulator archives, names, trademarks and underlying architectural works are
not relicensed by this release. No reference photographs or simulator meshes
are included. The models are visual approximations, not surveys or engineering
documents. The model license covers each contributor’s rights in their original contributions.
The Codriver helmet identifies the project; its inclusion does not grant trademark rights or imply endorsement.
