Geology and Environmental Geosciences

Landsat imagery, courtesy of NASA (National Aeronautics and Space Administration) Goddard Space Flight Center and the United States Geological Survey (USGS/NASA Landsat) is the longest continuous space-based record of Earth's land in existence, spanning 1972 to the present. This gallery includes all Landsat images published on the Earth Observatory, Visible Earth, and Landsat Science web sites from all seven Landsat satellites. Landsat data offer information essential for making informed decisions about Earth's resources and environment.
