Earth Resources Observation and Science (EROS) Center

The U.S. Geological Survey's (USGS) Earth Resources Observation and Science (EROS) Center in Sioux Falls, South Dakota, is a global leader in land imaging, using remotely sensed data to track how Earth is changing. EROS provides reliable, science-based information to help decision-makers understand how shifts in land use, cover, and condition affect people and the environment. 

This work is supported by an authoritative national archive of Earth observation data—housing more than 85 years of satellite and aerial records, including the complete Landsat collection. As the operational home of Landsat 8 and 9, EROS delivers daily observations that inform natural resource assessments, support national security, and help communities prepare for the future.

Origins, evolutions, and future directions of Landsat science products for advancing global inland water and coastal ocean observations Origins, evolutions, and future directions of Landsat science products for advancing global inland water and coastal ocean observations

In April 2020, the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center introduced a Level 2 provisional Aquatic Reflectance (AR) product for the Landsat 8 Operational Land Imager (OLI), marking the initial phase in developing a standardized global product for Landsat-derived surface water measurements. The goal of USGS EROS aquatic product research and...

A laboratory-based spectrometer intercomparison for the measurement of snow spectra A laboratory-based spectrometer intercomparison for the measurement of snow spectra

Seasonal snow is an integral component of global hydrological systems, global energy budget and Earth's climate. As an important part of many Earth systems, seasonal snow is also an essential source of water for many human populations and ecosystems around the world. As such, the measurement of seasonal snow and characterization of uncertainty in those measurements is crucial. To...

USGS Sagebrush Science: Supporting Public Safety and Economic Decision Making Across the West

The sagebrush biome is one of the largest ecosystems in North America. Encompassing nearly one-third of the continental U.S., it provides critical resources for millions of Americans and a home for hundreds of plants and animal species in the West. Natural resource management in sagebrush ecosystems can be complex, and science can support management decisions by providing knowledge and tools to...
