.Every once in a while the government does something really great. The pictures taken from the Landsat satellite are such an example. They’re wonderful, artful and very beautiful. The satellite snaps pictures as it passes over the earth, and then the images of cities and the larger landscape are colorized to convey all kinds of scientific information: temperature, ocean currents, crops and land cover, deforestation, location of fires, before-and-after views of Katrina-affected land, erosion, the polar ice cover, atmospheric conditions, snow, altitude. The geographic information is accurate, while the colors—vivid, even garish, almost hallucinogenic (and you know the government will love that description)— are rendered in ways that allow clarity for the various geological disciplines. They’re a mapmaker's dream and an artist’s inspiration.

Here are a few of the ones I liked. The images are in the public domain (hey, we paid for them) with the credit noted at the bottom of this post. I pulled most of the images from the web simply by Googling “Landsat,” but you can see a more edited and informative grouping as part of an exhibition supported by the Library of Congress. And you can learn more about the project at NASA.
