2026-03-18 release notes
The bbox column fields (bbox.xmin, bbox.ymin, bbox.xmax, bbox.ymax) have changed to the Parquet physical type DOUBLE (64-bit floating point) instead of 32-bit FLOAT. This change works around an outstanding Athena bug affecting queries on nested float fields.
Overview
The 2026-03-18.0 release of Overture data and v1.16.0 of the Overture schema are now available. You can access the datasets, changelog, GERS registry, bridge files, and PMTiles on AWS and Azure at the paths listed below.
What's new?
The data changelog now includes columns_changed, capturing which properties changed, per feature. Also in this release, we've made several improvements to the pipeline architecture of the transportation theme, including adding several data quality improvements and fresher source data. This architectural change also lays the groundwork for integrating additional road network sources into Overture in the near future.
Deprecations
The categories property in the places schema is now deprecated and will be removed in the June 2026 release, replaced by the new basic_category and taxonomy properties. All three properties will be available until then to ease the transition for our users. The taxonomy documentation is here.
Getting the data and release artifacts
You can access this month's data and release artifacts by following the process outlined here. The paths to the data and release artifacts are listed below. We encourage you to ask questions and provide feedback on the Overture Maps Discussion forum on GitHub. You can also file issues and report bugs in our data and schema repositories.
