Release Notes

2024-04-16-beta.0 release​

Here are the highlights for what's new and updated in the Overture Maps 2024-04-16-beta.0 release. The "beta" designation indicates the data and schema are largely stable.

Overture Maps 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.

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) where as they had previously been distributed as Double (64-bit).

Deprecations​

In this release, we implemented a refactor of the admins theme called divisions. The divisions schema and data are now available. The two themes will coexist for two subsequent releases (May 2024 and June 2024), at which point divisions will fully replace admins. More information on why we made this change 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 schema for 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 remain 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 which had previously dropped level will now have that information.
  • Renamed at to between for ranged linear referencing.
  • Removed mode_not scoping.

Previous releases

2024-03-12-alpha.0 release​

Here are the highlights of what's new and updated in Overture's 2024-03-12-alpha.0 release. This release includes a schema change from camelCase to snake_case for all property names and enumeration member names, an expansion of stable GERS IDs and incremental updates to the schema and datasets. More detailed schema release notes and a changelog are available in the OvertureMaps/schema.

Breaking changes​

We changed camelCase to snake_case in the schema for properties to be more compatible with some SQL engines. This may break existing code and queries. See here for an example of how this breaking change affects a query to the Admins dataset.

Deprecations​

In the April 2024 release, Overture will implement a refactor of the Admins theme called Divisions. Admins and Divisions will coexist for three releases, at which point Divisions will fully replace Admins. More information on this change here.

Theme-specific updates​

The data sources for each theme are cited here.

Transportation

  • Refreshed to include OSM data up to 2024-03-03.
  • Added ferry and alley segments.
  • Included 125K previously unsupported turn restrictions.
  • Added support for max weight, height, width and length access restrictions.
  • Added one-way road access restrictions.
  • Added road widths property to segments.
  • Acheived stability of GERS IDs for connectors and segments for this and future releases.
  • Note: data in the transportation theme is licensed under ODbL.

Administrative Boundaries (Admins)

  • Refreshed to include OSM data up to 2024-03-07.
  • Adapted schema to use snake_case to make attribute names more compatible with some SQL engines.
  • Correctly set locality types.
  • Made minor fixes:
    • All country localities now have ISO codes.
    • All non-country localities now have context property set.
  • Note: data in the Admin theme is licensed under ODbL.

Places

  • Achieved roughly 54 million place records.
  • Propagated stable GERS IDs from the previous release.
  • Made incremental improvements to accuracy and data quality.
  • Note: data in the Places theme is licensed under CDLA Permissive 2.0.

Buildings

  • Exposed the logic Overture uses to transform OSM tags into building attributes.
  • Made incremental improvements to further ensure the data conforms to the buildings schema.
  • Note: data in the Buildings theme is licensed under ODbL.

Base

  • Exposed the logic Overture uses to transform OSM tags into attributes in the land use, land and water data types.
  • Made incremental improvements to further ensure the data conforms to the base schema.
  • Note: data in the Base theme is licensed under ODbL.
