Earth as Art 3: A Landsat Perspective
This exhibition showcases Landsat 7 images created by the United States Geological Survey. Since 1972, Landsat satellites have collected from space information about Earth’s continents and coastal areas, enabling scientists to study many aspects of the planet and to evaluate changes caused by both natural processes and human practices. The images on display are actual digital photographs of the Earth, created by printing visible and infrared data in colors visible to the human eye.
Landsat imagery depicts the intricate beauty in Earth’s natural patterns. Band combinations and colors were chosen to optimize their dramatic appearance. Cloud formations, coastlines, mountain ranges, islands, deltas, glaciers, and rivers seen from space take on patterns resembling fantastically abstract art with their striking textures and brilliant colors.
After the exhibition closes, these images will remain in the permanent collection of the Library of Congress Geography and Map Division, which houses more than 5.5 million cartographic objects.
