Data & sources
Dromopedia combines open datasets into one record per airfield. Every entry lists which source each value came from and when that source was last imported; see the Data tab on any entry, for example London Heathrow. The licences below apply to what you see.
What the marks mean
The atlas has no edit queue of its own yet. Fix data where it comes from: codes, runways and frequencies on OurAirports (every airport page there has an edit link), dates, operators and names on Wikidata, photos on Wikimedia Commons. The atlas picks up the change on its next rebuild.
From Wikimedia Commons, with author and licence under every image. Files licensed only under the GFDL are not shown for now.
Any view of the register can be downloaded as CSV: filter it, then press Download CSV.
