The committed seed (`data/cells.parquet` and `data/sources/*.parquet`) contains only derived per-cell indices computed from the sources listed below. No raw data from any upstream dataset is redistributed.
GEM's Global Earthquake Model Foundation global seismic hazard map was evaluated and excluded because its CC BY-NC-SA licence bars commercial reuse.
