Landsat Science Archive
Mar 31, 2015 • The International Charter is a system that supplies free satellite imagery to emergency responders anywhere in the world. The Charter concept is this: a single phone number is made available to authorized parties providing [...]
Mar 31, 2015 • 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. The project goal was to remove access barriers to [...]
In 2008, the U.S. Geological Survey took 3.6 million images acquired by Landsat satellites and made them free and openly available on the Internet.
Last Thursday, Amazon Web Services (AWS) announced that it is now hosting Landsat 8 imagery on its publicly accessible Simple Storage Service (S3).
Landsat is a key data input for many products developed and used in water resources, agricultural monitoring, land use and land cover monitoring, forest management, and development planning.
A NASA study of a basin in northwestern Wyoming revealed that the snowmelt season in the area is now ending on average about sixteen days earlier than it did from the 1970s through the 1990s.
The federal government has invested billions of dollars to ensure our country's leadership in space-based observations of our planet. We need a workforce that is fully prepared to understand and use this data for solving problems of local, [...]
On March 13, 2015 at 4:00 pm CT, processing of Landsat 8 Thermal Infrared Sensor (TIRS) data resumed. The newly processed data includes the revised Calibration Parameter Files established after the mechanism control electronics (MCE) swap on [...]
The Landsat 8 Thermal Infrared Sensor (TIRS) resumed normal imaging operations.
After extensive investigation and testing, the decision has been made to switch the TIRS Mechanism Control Electronics from the primary to redundant side on Monday, March 2, 2015.
The rate at which tropical forests were cut, burned or otherwise lost from the 1990s through the 2000s accelerated by 62 percent, according to a new study which dramatically reverses a previous estimate of a 25 percent slowdown over the same [...]
A trio of Landsat calibration scientists—Brian Markham (NASA Goddard Space Flight Center), Jim Storey (Stinger Ghaffarian Technologies for USGS EROS) and Ron Morfitt (USGS Earth Resources Observation and Science Center) Landsat 8 Special Issue [...]
The latest edition of the National Land Cover Dataset (NLCD 2011) for Alaska is now publicly available. The extensive NLCD database continues to add to our understanding of where land cover change has occurred across the Nation over time. [...]
On February 11, 2013, the Landsat 8 satellite rocketed into space to extend a four-decade legacy of Earth observations. A few months after launch, we published a composite of images that spanned 9,000 kilometers of land from Russia to South [...]
Iran’s Lake Urmia is one of the largest saltwater lakes in the world. With eight times as much salt as seawater, it’s the globe’s largest habitat for brine shrimp, which attract flamingos, egrets and other birds as they migrate across Asia. But [...]
Two years ago today, Landsat 8 blasted off from Vandenberg Air Force Base!
USGS released provisional Landsat surface reflectance products in December. Surface reflectance products correct for atmospheric distortions thereby providing “less hazy” images.
When viewed from space, clouds largely obscure the Earth. It isn’t a matter of time of day, angle or distance. It’s just the way it is – unless, of course, you are gazing at the planet using Google Earth. The story of how Google Earth offers [...]
On December 19 the TIRS instrument on Landsat 8 was reconfigured due to detection of anomalous current levels associated with the scene select mirror encoder electronics. Since that time substantial testing has been conducted to isolate the root [...]
Turkana County in northwest Kenya has been reeling from several years of crippling drought. As a consequence, the nomadic peoples in the region have suffered. Livestock such as goats and cattle, the sole source of income for these pastoralists, [...]
