My point is, two thirds of the surface of the earth is water. Oceans have maybe two or three zoom levels. Given the fractal nature of the data, your estimate of "16 levels" as the global average is waaaaaay off base. I'd be very surprised if all the unique graphics for all modes ends up being more than 1 terabyte.
The landsat data alone comes close to 1TB. And that is just the whole world in the broad 30m or so array. (I know, because waaay back, i mirrored part of the Nasa WorldWind data)
This data is in no way fractal in nature.
And just do the math (just to see that your argument is bogus):
A km^2 at level 20 has 4^4=256 times as much data as one at level 16. If you do the math, central europe alone is enough to push the world to an average of level 16 (germany, e.g., is completely covered in airplane

Google Maps' database is far bigger...
A base of 8 tiles, with each becoming four more smaller tiles, in two modes (map/satellite), and 16 zoom levels.
Each tile is approx. 30kB.
(((0.03* (8 * (4^16)))/1024)/1024) == 983.04TB right there.
My calculator doesn't handle numbers big enough for streetview. O_O

We are sorry, but we don't
have maps at this zoom
level for this region.
Try zooming out for a
broader look.

There's actually 20 zoom levels, but I'm approximating 16 as the average.
