# Source attribution and licensing

This collection has mixed source terms. `license: other` and the label
`mixed-source-terms` describe that fact; they do not create a new blanket license.

## Global Streetscapes data and derivatives

The tabular Global Streetscapes source is provided by the NUS Urban Analytics Lab
and attributed to Hou et al. (2024), DOI
[10.1016/j.isprsjprs.2024.06.023](https://doi.org/10.1016/j.isprsjprs.2024.06.023).
The [upstream repository](https://huggingface.co/datasets/NUS-UAL/global-streetscapes)
identifies its license as
[Creative Commons Attribution-ShareAlike 4.0 International](https://creativecommons.org/licenses/by-sa/4.0/)
([legal text](https://creativecommons.org/licenses/by-sa/4.0/legalcode.en)).
Global Streetscapes data and their derivatives in this collection retain that
license and source attribution. Changes here include city subsetting, coordinate
and capture-sequence joins, explicit scene-label remapping, spatial partitions,
exclusions, processed numerical inputs and derived diagnostic labels. The source
measurements are attributed to the upstream providers.

The upstream imagery originates from third-party street-view providers; no
original street-view photographs are redistributed in this bundle. This bundle
does not grant rights to fetch or redistribute photographs under new terms.

## IBGE census data and boundaries

IBGE (Instituto Brasileiro de Geografia e Estatística) is the source of the 2022
census-tract income data, census-tract boundaries and FCU boundaries used in the
independent Brazilian analysis. The income table version dated 2026-05-08 retains
2022 as its census reference year. Official download URLs, release information,
file hashes and variable definitions are retained in `source_provenance.json`
and the archive's IBGE manifests and dictionaries. Joined tables, spatial
aggregations and evaluation results are derived analyses, not official IBGE
findings. Original IBGE notices and applicable source terms remain in force;
this collection does not declare IBGE material to be CC BY-SA or public domain
and does not grant a substitute license on IBGE's behalf.

## Category vocabulary, software and documentation

The official Places365 category vocabulary is attributed to the
[MIT CSAIL Places project](https://github.com/CSAILVision/places365); any original
notices remain applicable. No Places365 model weights are included.

No new open-source code license or blanket license over the original scripts,
reports and documentation is granted by this bundle. Source availability does not itself
imply an MIT, Apache, public-domain or other software license. Existing
third-party notices and licenses are not displaced. Dependencies remain under
their respective licenses.

For source-specific provenance, consult `source_provenance.json` and
`archive_file_descriptions.csv`. Keep the attribution and change notices with
redistributed source-derived data.
