US Navy Map of Future America ?

I have been seeing quite a bit of the "US Navy Map of the Future" since the Japan earthquake and tsunami.
Does anyone actually know where this came from?
All I have been able to find is the map itself and people saying it came from the Navy.
Anybody have a link actually linking it to a Navy or US Government site?

The map looks very similar to the "I Am America" map put out by Lori Toye in 1989.
Loris says that she gets her info from four spirit beings or "master teachers".

 Then of course you have Gordon-Michael Scallion's Future Map of the United States that came out in 1993.
Gordon says that he has the "gift of prophecy" like Nostradamus and Edgar Cayce.

The booklet The New Earth by Aron and Doris Abrahamsen also has it's own map.
Electrical Engineer Aron and his wife Doris come by their info via readings.
Aron Abrahamsen is also the author of "On Wings of Spirit" and "Holiday in Heaven".

Here we have Dolores Cannon's Nostradamus Map.
Dolores Cannon is a past-life regressionist and hypnotherapist.

This one is Ashton Pitre's map.
Ashton has been receiving psychic messages since the 1950s.

Here we have a map by Chet Snow, Ph.D.
Chet is an author, lecturer and a regression therapist.

Looking at them, they all look pretty similar don't they?
The question here is, what came first?
The chicken or the egg?

As far as I can tell, the oldest map of Earth Changes would be Edgar Cayce.
Well, I don't really know that he drew a map.
But he did make a pretty detailed prediction about the US changing including this...

“As to the changes physical again: The earth will be broken up in the western portion of America. The greater portion of Japan must go into the sea. The upper portion of Europe will be changed as in the twinkling of an eye …” Edgar Cayce reading 3976-15

Of course some have pointed out that these events were supposed to occur in 1934 to1936 and that maybe he wasn't talking about actual physical changes then.
