[OSM-talk] Announcing Daylight Map Distribution

[Michal Migurski]

Thanks for your feedback, Christoph.

The “100%” is accurate because there’s no data released in Daylight that hasn't previously passed through the OSM.org <http://osm.org/> database. When we observe errors and fix them manually, we make our edits to OpenStreetMap like any other editor.

I’m not sure I fully understand your second question, hopefully you can elaborate!
