Earth Resources Observation and Science (EROS) Center


At the USGS EROS Center, we study land change and produce land change data products used by researchers, resource managers, and policy makers across the nation and around the world. We also operate the Landsat satellite program with NASA, and maintain the largest civilian collection of images of the Earth’s land surface in existence, including tens of millions of satellite images. 

What's New at EROS?


Eyes on Earth is a podcast covering a range of topics on remote sensing, satellite operations, and the science of Earth observation. Watch for new episodes every two weeks.

EROS Fire Scientists Look at Potential Use of Lidar for Operational Burn Mapping

Fires that rage through forests, consuming vegetation on the ground and spreading into canopies, almost always leave important questions behind when they are done.

Like, what in fact burned? Where did it burn? How intense was the burn? And how far into the canopy did it reach?

Space Debris Remains Ongoing Concern for Landsat, Other Satellites

Space, it turns out, can be a messy place.

Sixty years of manned and unmanned space flight have left a cosmic junkyard circling the planet. From spent boosters to the detritus of defunct satellites, collisions, and explosions, there are countless potential cataclysms waiting to happen as space debris travels at relative velocities approaching 18,000 miles per hour.

Quantifying western U.S. rangelands as fractional components with landsat

Quantifying western U.S. rangelands as a series of fractional components with remote sensing provides a new way to understand these changing ecosystems. Nine rangeland ecosystem components, including percent shrub, sagebrush (Artemisia), big sagebrush, herbaceous, annual herbaceous, litter, and bare ground cover, along with sagebrush and shrub...

Evaluation of hydrologic impact of an irrigation curtailment program in the Upper Klamath Lake Basin using Landsat satellite data

Upper Klamath Lake (UKL) is the source of the Klamath river that flows through southern Oregon and northern California. The UKL basin is home to two endangered species and provides water for 81,000+ ha (200,000+ acres) of irrigation on the United States Bureau of Reclamation (USBR) Klamath Project located downstream of the UKL basin. Irrigated...
