Earth Resources Observation and Science (EROS) Center

Home

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.

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.

AVHRR Played Key Role in Influencing Trajectory of EROS Science

A few months back, in the fall of 2019, a handful of current and former staffers from the Earth Resources Observation and Science (EROS) Center met at a gathering spot in Sioux Falls to remember an old friend.

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 spp), big sagebrush, herbaceous, annual herbaceous, litter, and bare ground cover, along with sagebrush and shrub...

Earth as art 6

Earth has a stunning variety of landscapes. The colors, patterns, textures, and shapes all make for intriguing artwork as seen from the perspective of space.Earth As Art shows not only what satellites capture in the visible wavelengths of light you and I can see, but also what’s hiding in the invisible wavelengths that Landsat sensors can detect...

Validating a landsat time-series of fractional component cover across western U.S. Rangelands

Western U.S. rangelands have been quantified as six fractional cover (0%–100%) components over the Landsat archive (1985–2018) at a 30 m resolution, termed the “Back-in-Time” (BIT) dataset. Robust validation through space and time is needed to quantify product accuracy. Here, we used field data collected concurrently with high-resolution satellite...
