Facebook is releasing a third update to Daylight, our complete, downloadable preview of OpenStreetMap data.
📥 Download Daylight Map Distribution right now in OpenStreetMap PBF format: 📦 planet-v0.3.osm.pbf (57GB).
Earlier this year, Facebook released Daylight as part of our work with OpenStreetMap. We use maps to let our users find friends, businesses, groups and much more. OpenStreetMap (OSM), the open source wiki map, has a substantial global footprint of map data built and maintained by a dedicated community of global mappers making OSM a natural choice for Facebook.
Every day, our mapping teams work to confirm OSM’s millions of community contributions for consistency and quality by excluding intentional and unintentional edits that are incompatible with our use cases. Daylight is the result of that process.
With this third release, we’ve continued our collaboration with the Microsoft Building Footprints project on an extension to Daylight. Users of Daylight can continue to apply missing building footprints in the United States, Canada, Uganda, and Tanzania to render more complete-looking maps:
Larry Freil at Microsoft has posted a detailed exploration of this data, including suggestions for how to apply buildings data to Daylight for rendering OpenStreetMap with Mapnik. Microsoft provides the building footprint data under the Open Data Commons Open Database License (ODbL).

Throughout the remainder of this year, we will continue to publish releases of Daylight and conflated building footprints files from Microsoft approximately each month. Additionally, we will release details of the OSM tags we consider for inclusion in Daylight after converting them to a format suitable for use with existing community data tools.
- Daylight planet files are composed of 100% OSM data, released under the terms of the Open Database License
- We’ve checked public OSM changes contained in the distribution, and allowed only those which have been evaluated through validation algorithms and manual processes against commonly identified use-cases to provide the best mapping experience to our display maps
- We publish the data in PBF and OSC formats, common file formats universally supported by OSM tools and already used for planet-scale file distribution
How To Reach The Team
If you have any questions about this data distribution, we have created a #daylightdistro_feedback Slack channel in OSM US. Members of the team will be there periodically to answer questions. You can also email the team at email@example.com.
