In the US at least, NAIP would make for a good base dataset.

Amazon has indicated they would be willing to help us with this kind
of project, but I agree that a distributed registry approach makes
the
most sense in the short/medium term, and think we should focus our
efforts there.
I also think it is a good idea to distribute the server data
regionally
to spread the storage requirements. Also what about the idea of
using
NASA data that is in World Wind ? Not sure if it is totally free
in use
but it could provide a "base" set of aerials just like the Tiger
files
provide a base set of roads in OSM.
There's a lot of different bases there. Landsat data is global 15m
data. Blue
Marble is a commonly used 'world scale' map, decent down to 1:1M
scale, etc.
You'll probably need to be more specific about which NASA dataset
you're
talking about.
OAM had both blue marble, and an i-Cubed colorized landsat dataset,
as its
two main bases.

1. discover current hosting and hardware details.
2. establish future hosting and hardware requirements and wish

n. meet in person, raise toasts.
We should heed crschmidt's message. The amount of data is vast.
Besides a registry of where data is, a federated approach could
include
having parts of the imagery hosted in various places. I could
see a few
people in mass getting together to host massgis orthophotos, and
other
regions doing that too. Using the OSM model, the goal would be
to have
the overall structure and indices, and also available tools to
enable
others to host parts of the entire dataset with minimal effort.
