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.

Towards affordable wetland evapotranspiration monitoring using the Variance-Bowen Ratio method: Insights from three contrasting wetlands Towards affordable wetland evapotranspiration monitoring using the Variance-Bowen Ratio method: Insights from three contrasting wetlands

Accurate measurement of evapotranspiration (ET) is essential for sustainable water management. Standard methods such as eddy covariance (EC) are costly, while alternatives such as surface renewal are cheaper but require calibration and complex data processing. This study evaluates the utility of the Variance-Bowen Ratio (VBR) method for estimating ET across three California’s wetlands...

A framework for integrating spatiotemporal deep learning methods with landsat for annual land cover and impervious surface mapping A framework for integrating spatiotemporal deep learning methods with landsat for annual land cover and impervious surface mapping

Land cover information is essential for understanding Earth’s surface dynamics and how vegetation, water, soil, climate, and terrain interact. The National Land Cover Database (NLCD) has been the authoritative source for consistent U.S. land cover mapping. To extend NLCD’s temporal resolution and reduce production latency, we developed the Land Cover Artificial Mapping System (LCAMS)—a...

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...
