NASA Global Climate Change: Earth as art

http://climate.nasa.gov/news/746/

Built by NASA and operated by USGS, Landsat satellites supply Earth scientists, land-resource managers, and policy makers with objective data about changes across the global landscape. Some changes, like major floods or volcanic eruptions, come quickly; others, like urban sprawl or regrowth from forest fires, appear gradually. Landsat impartially records these and many other changes to the land that are induced by man or nature.

Beyond the scientific information they confer, some Landsat images are simply striking to look at — presenting spectacular views of mountains, valleys, and islands; forests, grasslands, and agricultural patterns. By selecting certain features and coloring them from a digital palate, the USGS has created a series of “Earth as Art” perspectives that demonstrate an artistic resonance in land imagery and provide a special avenue of insight about the geography of each scene.
