Nov 27, 2015Animating the “Karakoram Anomaly” with Landsat

Nov 27, 2015 • Capitalizing on the long Landsat data record and the human brain’s capacity to recognize movement, Frank Paul from the University of Zurich has created glacier animations that enable viewers to witness the complex flow of [...]

Oct 28, 2015Despite Warming, Landsat Reveals Decadal Slowdowns on Greenland Ice Sheet

Ice sheets are in perpetual motion, making their way downslope like a river. If the amount of snow that an ice sheet accumulates does not keep pace with its loss to the sea, sea level will rise. As temperatures have climbed, positive feedback [...]

Oct 5, 2015A forest by any other name?
Semantics, carbon implications, and solutions

Using the world’s first global, Landsat-based 30-meter resolution map of tree cover, researchers found that ambiguity of the term “forest” has the potential to create 13 percent discrepancies in forest area maps. While ecologists have long [...]

Landsat Benefited U.S. Economy by $1.8 Billion in 2011
Aug 30, 2015Landsat Benefited U.S. Economy by $1.8 Billion in 2011

The 2.38 million Landsat images freely downloaded in 2011, benefited the U.S. economy by $1.8 billion found a new study published this month by a team of economists from Colorado State University and the USGS Fort Collins Science Center.

Forester showing pine beetle damage
Aug 19, 2015Improved Forest Disturbance Monitoring via an Algorithm Ensemble

Forest resource managers, natural resource policy makers, and global change scientists need comprehensive, consistent, and up-to-date information on trends in forest cover and condition. This information is essential for understanding carbon [...]

North American river widths derived from Landsat
Jul 9, 2015A Satellite View of River Width

Hydrologists from the University of North Carolina have come up with an innovative way to estimate the size of rivers via satellite images. Combing through data acquired by Landsat satellites, George Allen and Tamlin Pavelsky have compiled a new [...]

Percent loss of Turkey's glaciers
Jul 2, 2015Turkish Glaciers Shrink By Half

Researchers and citizens have known for some time that Turkey’s glaciers are shrinking. Now scientists have calculated the losses and found that more than half of the ice cover in this mountainous country has vanished since the 1970s.

Mar 31, 2015Holding the Key—Australia Unlocks Its Landsat Archive

In Australia, the Unlocking the Landsat Archive (ULA) project has created a "living and accessible" archive of Landsat 5 and 7 data, for years 1998–2012.

Mountain pine beetle destruction
Mar 7, 2015Landsat-Based Insect Atlas Gives Best View of Outbreaks in Forests

Scientists for the first time have simultaneously compared widespread impacts from two of the most common forest insects in the West—mountain pine beetle and western spruce budworm – an advance that could lead to more effective management policies.

Dec 19, 2014U.S. Forest Service Uses Landsat to Improve Estimates of Forest Disturbance

Each year the U.S. Forest Service takes a census of trees, chronicling the nation’s forest heath and timber resources. Forest managers use this information to project what U.S. forests will be like in coming decades and, if needed, to adjust [...]
