Announcing an Update to Daylight Map Distribution

Jul 16th, 2020

This announcement was originally published as an OSM Diary post.

Facebook is releasing an update to Daylight, our complete, downloadable preview of OpenStreetMap data.

📥 Download Daylight Map Distribution right now in OpenStreetMap PBF format: 📦 planet-v0.2.osm.pbf (56GB).

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.

Daylight Map Distribution

With this second release, we’ve also collaborated with the Microsoft Building Footprints project on an extension to Daylight. This extension includes buildings detected from aerial imagery in the United States, Canada, Uganda, and Tanzania. These building datasets were conflated with this Daylight Map Distribution to only add missing footprints, and provided as a changeset to Daylight in OSC format. Users of Daylight can now easily expand coverage to include additional AI-generated building footprints not found in OSM or mapped via the RapiD editor. Microsoft provides the building footprint data under the Open Data Commons Open Database License (ODbL).

After our initial announcement of Daylight, the community asked about future plans. With this second release, we plan to establish a regular cadence of releases tracking OSM changes into the future, to ensure that upstream changes to OSM are available with minimal delay.

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 osm@fb.com.
