Base URL

Endpoints 6

• GET/catalog.jsonAll releases (child links) and the newest (latest; 16 Oct 2026: 2026-09-23.1), plus the GERS registry on S3.
• GET/{release}/catalog.jsonOne release: schema version (2.0.0) and the six themes: addresses, base, buildings, divisions, places, transportation.
• GET/{release}/{thema}/{type}/collection.jsonOne type (building, building_part, place, address, segment, connector, division, division_area, division_boundary, land, land_use, land_cover, water, infrastructure, bathymetry): licence, row count, columns, items.
• GET/{release}/{thema}/{type}/{nnnnn}/{nnnnn}.jsonItem per file: bbox it covers, num_rows, and the assets aws and azure with address and file:size.
• GETs3://overturemaps-us-west-2/release/{release}/theme={thema}/type={type}/*.zstd.parquetThe GeoParquet files themselves (also via https://overturemaps-us-west-2.s3.us-west-2.amazonaws.com/… and Azure overturemapswestus2). Read them with DuckDB and filter on the bbox column.
• GEThttps://tiles.overturemaps.org/{release}/{thema}.pmtilesVector tiles per theme as PMTiles, readable with HTTP Range (buildings 180.7 GB, places 18.4 GB).

Filtering tested

No search API: the STAC is static (no /search, no queryables). Pick the file via the item bbox, or filter in SQL (DuckDB) on the bbox column and on fields such as class, subtype, country.

Parameters 3

Columns in the GeoParquet files (selection, schema 2.0.0) 10

Limits and pitfalls

• No rate limit documented. The files are large: a buildings file is ~525 MB with ~4.9 mln rows; read with a bbox filter or HTTP Range instead of downloading everything. tested
• Releases stay online for at most 60 days (GDPR). A URL with a release number therefore only works for two months; always start from latest in catalog.json. experience
• A HEAD request on a PMTiles file returns HTTP 400; a Range request (bytes=0-126) does work (206, with the total size in Content-Range). tested
• The STAC collections of places and addresses only say license 'other' with a link to the attribution page; the licence differs per source (places e.g. CDLA Permissive 2.0, Apache 2.0; addresses per country). tested
• Items follow a global layout: one buildings file covers a large strip (central Netherlands sits in a file that also includes Germany). Check the item bbox before fetching anything. experience
• The S3 bucket can also be browsed: ?list-type=2&prefix=release/&delimiter=/ lists the release folders. No robots.txt on stac.overturemaps.org and tiles.overturemaps.org (404). tested
