Overture 2024-04-16-beta.0 Release Notes

Overture 2024-04-16-beta.0 is now available. Here are the highlights for what’s new and updated in this release. The “beta” designation indicates the data and schema are largely stable.

We encourage developers wishing to adopt Overture Maps base layers to begin evaluating and providing feedback on the data, schema, and GERS IDs. Depending on the feedback from this release and subsequent releases, we anticipate moving to a production release in the next few months.

Breaking changes​

We renamed the bbox column fields to align with the upcoming GeoParquet 1.1 spec.

minx → xmin
miny → ymin
maxx → xmax
maxy → ymax

The fields are all now Parquet Float (32-bit) whereas they had previously been distributed as Double (64-bit).

Deprecations

In this release, we implemented the schema for a refactor of the admins theme called divisions. The divisions data will be available in our May release. After that, the two themes will coexist for two additional releases (June and July), at which point divisions will fully replace admins. More information on why we made this change here.

Accessing the data:

Overture 2024-04-16-beta.0 is available in GeoParquet and stored on AWS and Azure. Users can select the data of interest and download it by following the process outlined here.

Theme-specific updates

See here for information about licensing and data attribution for each theme.

Administrative Boundaries Admins/Divisions

• Included OSM data up to 4/8.
• Implemented the divisions theme, which has a better-defined schema supporting perspectives, different types of polygons, and other new features.
• Note: see information above about the deprecation of admins.

Base

• Included OSM data up to 3/16 (sourced via Daylight Map Distribution v1.44).
• Included 46M water features, 55M land features, 40M land use features, and 48M infrastructure features.
• Maintained the original OSM tags on all features.
• Normalized and added elevation, surface, and wikidata as top-level properties.

Buildings

• Included OSM data up to 3/16 (sourced via Daylight Map Distribution v1.44).
• Included 2.35B conflated building footprints from OSM, Esri Community Maps, Microsoft ML Building Footprints, and Google Open Buildings.
• Made incremental improvements to further ensure the data conforms to the buildings layer schema.
• Added 3d attributes from OSM, such as roof shape.
• Note: The order of conflation is OpenStreetMap → Esri Community Maps → high precision Google Open Buildings → Microsoft ML Building Footprints → lower precision Google Open Buildings. For example, if Esri has a building that does not exist in OSM, we take that building, then we “fill-in” the rest of the map with any ML buildings that do not intersect with either OSM or Esri. We use the 90% precision confidence threshold to delineate between high and lower precision for Google Open Buildings, this threshold varies per s2 cell.

Places

• Included ~53 million place records.
• Included stable GERS IDs propagated from the previous release; roughly 51 million of the IDs are propagated and 2 million are new.
• Made incremental changes to improve the accuracy and quality of the dataset.

Transportation

• Included OSM data up to 4/7.
• Classified 12.2M segments as path.
• Added is_covered flag to denote partially enclosed segments.
• Improved scope merging; fewer access restrictions entries are now required.
• Fixed a projection issue affecting segment length calculation and linear referencing.
• Promoted class to a top-level property.
• Moved level property into road property to allow linear referencing. 84% of all segments that had previously dropped level will now have that information.
• Renamed at to between for ranged linear referencing.
• Removed mode_not scoping.
