Some interesting observations:

• The image is rather old, but I doubt anyone would be able to tell exactly how old it is, except maybe @LawVinsmoke.
• To the north-west from spawn we can see the British Railway system, that connects DirectorAnivian‘s base, DakotaReef / Bazurka‘s base, and Province of Canada.
• There are 4 types of claims: red claims, green claims, blue claims, and green claims with black borders. It doesn’t take long to realize that blue claims are administrator‘s, but what do other colors mean?
• As @Crazy Pirate mentioned in the original topic, some of the claims appear to be missing.
• Always wanted to build an island base? Use this map to find a free island!

Thanks to @GodsDead, @Crazy Pirate, and @LawVinsmoke:

• Green claims belong to inactive players (approximately 3 months).
• Green claims with black borders belong to inactive players, but they have some active trustees.
• Blue claims belong to admins.
• Red claims belong to active players.
• The claim data is about a week old, the map itself is a few weeks out of date (some time around January).
