See complete instructions on accessing Overture data in our documentation at docs.overturemaps.org.

We welcome feedback about Overture Maps data in the Discussions. Feedback on the data schema, is best provided in the discussions in the schema repository.

Overture Maps Data

Overture Maps data is available in cloud-native Parquet format. There is no single Overture "entire planet" file to download. Instead, the data is partitioned by both theme and type and made available on Amazon S3 and Microsoft Azure Blob Storage. Read more about Overture data and schema at docs.overturemaps.org

The latest data release is available at the following locations:

Parquet Schema

The Parquet files match the Overture Data Schema for each theme with the following enhancements:

  1. The id column contains unique identifiers in the Global Entity Reference System (GERS) format.
  2. The bbox column is a struct with the following attributes: xmin, xmax, ymin, ymax. This column allows you to craft more efficient spatial queries when running SQL against the cloud.
  3. The geometry column is encoded as WKB (the files are geoparquet).

Data Release Feedback

We are very interested in feedback on the Overture data. Please use the Discussion section of this repo to comment. Tagging it with the release and relevant theme name (Places, Transportation) will help direct your ideas. Please include as much detail as possible. The associated Task Force will carefully review each submission and offer feedback where required.
