Latest in Landsat - September 2023 - Vol. 2 | Issue 9
August marked the 50th anniversary of the USGS Earth Resources Observation and Science (EROS) Center! A cornerstone of the Landsat program, EROS maintains the largest civilian collection of images of the Earth’s land surface in existence, including over 11 million available Landsat Level-1 scenes.
USGS EROS Celebrates 50 Years of a Mission that Matters
Fifty years ago, the U.S. Geological Survey (USGS) brought people together to work in a new government facility surrounded by South Dakota farm fields. The mission: act as stewards for land remote sensing imagery, especially the scenes collected by the fledgling Landsat satellite, and help people around the world make sense of it to benefit themselves and the planet.
Eyes on Earth Episode 101 – EROS 50th: Director Pete Doucette Looks Ahead
In its 50th anniversary year, EROS received a new leader who celebrates the past while embracing the future.
EROS 50th History: Helping the World Through Science
Millions of people in the United States and billions around the world live unaware that employees of a far-off USGS facility surrounded by South Dakota farm fields are working every day, in many different ways, to help improve their lives—and have been for decades.
Landsat Ground Station Operators Working Group 51st Meeting Held in Norway
The USGS Landsat International Cooperator Network, in coordination with the Kongsberg Satellite Services (KSAT) and the Norwegian Space Agency (NOSA), met for the Landsat Ground Station Operators Working Group (LGSOWG) #51 meeting in Tromsø and Svalbard, Norway during the first week of August.
Validity of the Landsat surface reflectance archive for aquatic science: Implications for cloud-based analysis
Originally developed for terrestrial science and applications, the US Geological Survey Landsat surface reflectance (SR) archive spanning ~ 40 yr of observations has been increasingly utilized in large-scale water-quality studies. These products, however, have not been rigorously validated using in situ measured reflectance. This letter quantifies and demonstrates the quality of the SR products by
Landsat Calibration & Validation
While Landsat satellites are well-designed and calibrated prior to launch, continuous calibration is required to offset degradation that may be caused by mechanical or electrical effects, or exposure to UV radiation. Calibration requires a comparison between the measuring instrument and an absolute reference standard of known accuracy. Validation of Landsat data is an ongoing effort.
