Landsat Collection 2 Reprocessing of Landsat 8 Images Acquired in 2015

During Landsat Collection 2 data processing in 2020, several Landsat 8 images acquired from November 1 and November 2, 2015 were processed to Level-1 products with misaligned Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) spectral bands. These images were quickly identified and removed from the USGS archive soon after the release of Collection 2 on December 1, 2020.

EROS Rangeland Tools Aid Western U.S. Land Managers

The extensive rangelands across the Western United States are threatened by invasive grasses, climate change, and altered fire regimes that can disturb the landscape. The largely semi-arid lands are also important for the survival of species that need undisturbed sagebrush ecosystems to thrive.

Landsat will help U.S. and Canada Share River’s Water

A river meanders serenely through the northern prairie, waters flowing eastward. The scene’s simplicity belies the complex nature of how the water is used—especially when the river flows from one country to another and back.

Landsat Science Team's Crystal Schaaf Discusses Albedo, Its Importance, and How It Can Affect Climate

One of the interesting fields in remote sensing science is the study of albedo, a term derived from the Latin word for whiteness. Albedo is another name for reflectivity. The albedo of a surface determines how much sunlight will be absorbed and warm the surface compared to another surface that reflects most of the light and does not change temperature.

High Resolution Imagery Captures Growth in South Dakota’s Largest City

The high-tech hub that is the USGS Earth Resources Observation and Science (EROS) Center was carved out of a chunk of rural farm ground nearly 50 years ago, and the Center still counts more cows and cornstalks than human beings as neighbors.
