Interessante. Da notare anche il tipo di licenza che è stata scelta.
mailseth writes "I'm happy to announce the release of my new true color
global dataset: True Marble. It's a global 15m, 3 terabyte, dataset
which concentrates on reproducing the natural color of the landscape
while maintaining the contrast required to distinguish small features. I
think it's much more realistic than other similar products out there.
I've released a 250m resolution version of True Marble under a Creative
Commons license.
We're also releasing True Marble GLCD, a global 15m land cover dataset.
This is a highly experimental, but first of its kind, dataset. I've been
in contact with a professor and am planning on starting a PhD in the
fall to study the algorithm I used. The accuracy isn't the best, but
that's what makes it experimental. 
I'm also releasing a free 250m
version of the True Marble GLCD."
Ciao,
Steko
