Eyes on Earth Episode 50 – Delaware River Basin

About 15 million people rely on the Delaware River Basin for drinking water, including residents of Philadelphia, PA, Camden, NJ, and Wilmington, DE. What might happen to the water supply if climate change and population growth continue unabated? How might that impact land cover and land use patterns? Those are the kinds of questions scientists at EROS looked to answer in

Landsat in the Cloud: COGs and Notebooks

In the past, users spent 80% of their time downloading and preparing Landsat data to be processed. With Landsat in the cloud, you can get direct access to stream the Landsat archive without the need to download large amounts of files, by leveraging the Cloud Optimized Geotiff, or "COG". COGs are just like the Geotiff that you're used to only unpackaged and internally tiled

Image of the Week - Wildfires Burn in the Shadow of Mount Rushmore

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.

Eyes on Earth Episode 49 – Fire Atlas

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

Terra MODIS & S-NPP VIIRS Observe Snowpack in Sierra Nevada Mt. Range

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

Image of the Week - Tides in the Bay of Fundy

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

Eyes on Earth Episode 48 – Satellites and the Forest Census

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

Image of the Week: Mudslide Cuts Through Big Sur Burn Scar

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

Landsat in the Cloud: LandsatLook 2.0

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

Eyes on Earth Episode 47 – Ladies of Landsat

Ladies of Landsat aims to help women and other underrepresented groups feel welcomed and supported in the field of remote sensing. The Twitter group has grown to 5,700 members and counting since Dr. Kate Fickas started it in 2018 during a Landsat Science Team meeting at EROS. In this episode of Eyes on Earth, we learn about the ambitions and actions of the group, why a
