OSM city extracts
OpenStreetMap for a few metro areas as GeoParquet, refreshed weekly, for DuckDB over HTTP range
requests. Rows are sorted along a Hilbert curve and carry a bbox column, so a query on a few blocks
reads only the row groups it needs.

Querying with DuckDB
INSTALL spatial; LOAD spatial; SELECT name, tags['shop'] AS shop, level FROM 'https://data.sisumaps.com/osm/toronto/latest/indoor.parquet' WHERE bbox.xmin > -79.64 AND bbox.xmax < -79.60 AND bbox.ymin > 43.67 AND bbox.ymax < 43.70 AND tags['shop'] IS NOT NULL;
Columns: id (way/123), osm_type, osm_id,
tags (a map of every tag), name, theme, level, a few promoted
tags in the subsets, geometry (WKB) and bbox. Use a dated build
(/osm/<city>/<YYYYMMDD>/…) for anything you keep; latest moves weekly.
Every build has a manifest.json with its sources, rows and checksums.
