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." See also related stories below.

Via AGISRS, here's two updates on the GlobCover dataset which provides free 300m-resolution land-use land-cover of global coverage. We discussed GlobCover about a year ago, the source data is not available but should be this coming July. You can browse the whole world GlobCover LULC data using the tool in the links above. From the ESA article: "Earth’s land cover has been charted from space before, but this map, which will be made available to the public upon its completion in July, has a resolution 10 times sharper than any of its predecessors. Scientists, who will use the data to plot worldwide land-cover trends, study natural and managed ecosystems and to model climate change extent and impacts, are hailing the product – generated under the ESA-initiated GlobCover project – as 'a milestone.'"
