## Microsoft Global ML Building Footprints data

The compact Mexico City and Tulsa building-envelope targets are derived from
Microsoft Global ML Building Footprints, dataset path version 2026-02-03.
Planetwide clips, quantizes, and compresses the source into modified PWCITY
descriptor data. The source and modified data are shared under the following
agreement.

## OpenStreetMap context data

The Mexico City and Tulsa `PWVECT1` context databases are altered derivatives
of OpenStreetMap data and are made available under the Open Data Commons Open
Database License (ODbL) 1.0.

Copyright notice: © OpenStreetMap contributors.

- OpenStreetMap copyright and attribution: <https://www.openstreetmap.org/copyright>
- ODbL 1.0 legal text: <https://opendatacommons.org/licenses/odbl/1-0/>
- Altered database copies: `data/city_vectors/mexico-city/context.pwvector`
  and `data/city_vectors/tulsa/context.pwvector`, with their `places.json` labels.
  The preview distributes these exact modified data through `planetwide-map-data.zip`.
  Earlier base packets are also available from
  <https://github.com/ThatGuySam/planetwide/tree/main/data/city_vectors>
- Transformation and source-snapshot record:
  `docs/research/city-vector-atlas/README.md`

`PWVECT1` remains physically separate from the Microsoft-derived `PWCITY1`
building-envelope database. The runtime packets contain quantized city-context
geometry, not the complete OpenStreetMap database.

## Natural Earth land data

`assets/maps/earth_land_110m.png` is a 512×256 one-bit land/water mask derived
from Natural Earth 4.1.0 1:110m land polygons through `world-atlas@2.0.2`.
Natural Earth data are in the public domain under the project's terms of use:
<https://www.naturalearthdata.com/about/terms-of-use/>.

The exact source version, source and output hashes, transformation steps, and
tooling licenses are recorded in `docs/art/earth-land-mask-provenance.md`. The
generation toolchain does not ship with the game.
