notes: |
  Columnar GeoParquet (Zstandard-compressed). Each theme/type is partitioned
  into ~5 part files (500–700 MB each). DuckDB httpfs can query directly from
  S3 without local download. Schema versioned per release; breaking changes
  between major quarterly releases. Geometry in WGS84 (EPSG:4326).
  Official STAC indexes allow AOI asset selection before querying the global
  partitions. Releases have short rolling retention (roughly two months), so
  reproducible products must retain pinned bronze inputs. Licensing is
  theme-specific; buildings are ODbL-1.0 and require attribution.
