"Earth as Art" features images from the Landsat 5 and 7, Terra, Aqua, and Earth Observing-1 (EO-1) satellites. All are among a fleet of U.S. environmental satellites used for scientific research and applied purposes. Instruments on these satellites measure light outside of the visible range. The images produced from these data reveal features and patterns not always visible to the naked eye. The Terra, Aqua, and EO-1 satellites are managed by NASA. Landsat satellites are managed by the U.S. Geological Survey.
The iPad version of "Earth as Art" allows users to zoom into the book's 75 satellite images and access additional information on selected features and the satellites used.”
