Location

Overture Maps data is available in cloud-native Parquet format. There is no single "entire planet" file to download. The data is partitioned by theme and type and hosted on Amazon S3 and Microsoft Azure Blob Storage.

Replace <release> below with a release version from the STAC, for example 2026-10-21.0.

Amazon S3

Parquet Schema

The Parquet files match the Overture Data Schema for each theme, with these additions:

1. The id column contains unique identifiers in the Global Entity Reference System (GERS) format.
2. The bbox column is a struct with xmin, xmax, ymin, and ymax. Filter on it to make spatial queries against cloud storage more efficient.
3. The geometry column is WKB-encoded (the files are GeoParquet).

Release Discovery

The Overture STAC (SpatioTemporal Asset Catalog) is the authoritative source for discovering releases and determining which is the latest.

The STAC also serves latest.ddb, a DuckDB file with one view per feature type over the latest release. It is linked from the root catalog.json. Run LOAD spatial; before querying it.

For upcoming release dates, see the release calendar (schema).

Feedback
