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.
A Decade from Above: Landsat Imagery from the 2010s
Another decade has come and gone.
The decade of the 2010s was a monumental one for the Landsat program, marking the first full decade of free and open data, the launch of Landsat 8, the release of...

The Landsat program and the USGS Earth Resources Observation and Science (EROS) Center have long held and important place in the nation’s Earth observation (EO) policy.
Meet the USGS Landsat Project Scientist and Landsat Science Team Co-Chair
Christopher “Chris” Crawford likes to say his roles with the U.S. Geological Survey (USGS) as a research physical scientist, the Landsat Project Scientist, and co-chair of the Landsat Science Team are akin to staring down a foot of snow on the driveway.

Global Study Finds Algal Blooms Intensifying in Freshwater Lakes Worldwide
A study of global freshwater algal blooms funded in part by a U.S. Geological Survey (USGS) Landsat Science Team (LST) Award has found that harmful blooms showing up more and more in various U.S. cities are intensifying in lakes worldwide as well.
International Cooperators Find Value, Collaboration in Joining Landsat Network
Landsat’s eyes in the sky captured a riveting story of rebirth across Australia’s central deserts this past spring of 2019.
Floodwaters from Queensland in north Australia killed an estimated 500,000 cattle and inundated homes before draining to the south, cascading over riverbanks and spilling across the floodplains toward the country’s lowest point at Kati Thanda-Lake Eyre.
