Earth Resources Observation and Science (EROS) Center

In late March of 2021, just four miles from the edge of South Dakota's second-largest city, two wildfires sparked by human activity burned through a section of the Black Hills.

The Schroeder fire began on March 29. It was fueled by high winds and dry conditions, spreading rapidly across more than 2000 acres, forcing the evacuation of neighborhoods and businesses.

Teams at the USGS EROS Center have completed fire atlases for nine National Parks across the U.S. Each atlas defines the size and severity of each fire in each park since 1984, including fires too small to be mapped by other programs. Yellowstone National Park has had nearly 100 fires, for example, ranging from a few acres to thousands of acres. The project used data from

The US Geological Survey's Earth Resources Observation and Science Center, or "EROS" archive’s data from the LandSat satellites which have been in operation from 1972 to the present day. EarthShots presents environmental changes using Landsat images. 
 

A small watershed restoration project proves that land farmed for half a century can be returned to a previous state. In 2002, Mike Osterholm bought 98 acres in northeastern Iowa, most of it annually tilled cropland. The land included the confluence of Duck Creek and Waterloo Creek. He observed soggy patches of ground during wet periods and marked the locations with flags

The Moderate Resolution Imaging Spectroradiometer (MODIS) sensor is located aboard NASA’s Terra and Aqua satellites. The Visible Infrared Imaging Radiometer Suite (VIIRS) sensor is aboard the Suomi National Polar-orbiting Partnership (S-NPP) satellite. Together these sensors provide us with over two decades of crucial data for studying changes that have occurred on the

The Bay of Fundy in Canada has a unique geography funneling the Atlantic Ocean into some of the world's highest tides. At some points the water level can rise and fall over forty feet. The water's edge at Minas Basin shown in these Landsat 8 images changes dramatically depending on the day and time. Because Landsat 8 passes over quickly, the imagery cannot reveal the

It’s possible to map vegetation type with Landsat, but getting the maps right requires more than satellites alone. The teams behind LANDFIRE use an extensive network of ground control points to check their work, thereby bolstering the reliability and utility of their multi-layer GIS product suite. On this episode of Eyes on Earth, we meet scientist Karen Schleeweis, who

A mudslide near the 2020 Dolan Fire's ignition point chopped through a chunk of California's scenic State Highway 1 in late January. 

The Dolan Fire began near Big Sur on August 18th, 2020. It scarred nearly 125,000 acres before being fully contained in December. 

The damage is clear in false color Landsat 8 imagery from August and October. The scar is still

With existing USGS tools you can search for scenes, view thumbnail browse images of scenes, and download scene-based data, all derived from the USGS archive of scene-based products. Now that Landsat scene data has been unpacked and stored in the cloud, LandsatLook 2.0 can access that data and present it to users in ways that were not previously possible. Thanks to the

The Earth As Art project began in the early 2000s, and its original intent remains the same: to produce images that do not look like satellite images at first glance. 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 in the infrared
