# Data-use terms for nuScenes-NRS derived artifacts

This file is a release notice, not a replacement for the official nuScenes
agreement. The official agreement is the controlling text:

* [nuScenes Terms of Use](https://www.nuscenes.org/terms-of-use)
  (non-commercial terms, last updated by Motional on 16 November 2021); and
* [CC BY-NC-SA 4.0 legal code](https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode).

The official terms expressly cover use of data derived from nuScenes. They
apply in addition to the conditions below, and prevail if there is any
conflict.

## Scope

These terms apply only to the files in this repository that were produced for
nuScenes-NRS: the PNG road masks, split/token lists, manifests, and related
documentation. They do not apply to the original nuScenes dataset, which is
not included here and remains governed by the terms published by the nuScenes
authors.

## Permission for the derived release

Subject to the official nuScenes terms and the third-party restrictions below,
the derived masks and split metadata may be downloaded, copied, modified, and
used for non-commercial academic research, teaching, and evaluation, provided
that users:

1. retain this notice and the attribution in `CITATION.cff`;
2. identify modifications to the derived masks or split files; and
3. do not present the masks as the original nuScenes annotations.

Commercial use, resale, or redistribution as part of a commercial dataset or
product is not permitted by the non-commercial terms; obtain the appropriate
commercial license from Motional before such use. This repository does not
grant a commercial exception.

## Third-party data boundary

No original RGB image, LiDAR point cloud, lidarseg file, calibration, pose,
depth, or normal file is licensed or redistributed by this repository. A user
who regenerates masks must independently download nuScenes, satisfy its
license and attribution requirements, and comply with any applicable
data-protection or export rules. Some third-party data in nuScenes may carry
separate restrictions and may not be redistributed. Motional's names,
trademarks, logos, and endorsement are not granted by this release.

## Scripts
