A reproducible table of OSM features organized into 10 high-level themes (buildings, water, land use, etc.), published as Parquet files on the AWS Open Data registry and queryable in place, with a quadkey per feature and precomputed joins like landuse-for-each-building. It adds validated attributes (cleaned building heights, simplified place classes), boolean flags (indoor, bridge, intermittent), and examples you can run: query “water” for all water bodies, “parks” globally, or count buildings by state using simple SQL against the Earth tables.
