Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support.

U.S. Landsat Analysis Ready Data
U.S. Landsat Analysis Ready Data (ARD) are a revolutionary new U.S. Geological Survey science product that allows the Landsat archive to be more accessible and easier to analyze and reduces the amount of time users spend on data processing for monitoring and assessing landscape change. U.S. Landsat ARD are Level-2 products derived from...
In 2016, the U.S. Geological Survey reorganized the Landsat archive into a tiered collection structure, which ensures that Landsat Level-1 products provide a consistent archive of known data quality to support time-series analyses and data “stacking” while controlling continuous improvement of the archive and access to all data as they are...
Landsat brings understanding to the impact of industrialization
In his 1963 book, “The Quiet Crisis,” former Interior Secretary Stewart Udall lamented what he called the decline of natural resources in the United States under the advancements of industrialization and urbanization.
Landsat helps bolster food security
One of the cruelest, most complex narratives in the world today (2016) is written in the hunger of sub-Saharan Africa. When famine is the only yield from the scorched Earth, survival often depends on a heart-rending calculation—how far is the distant feeding center; how close is the nearest well.
Landsat plays a key role in reducing hunger on earth
The United Nations’ Department of Economic and Social Affairs predicts 9.7 billion people will sit down every day to the global dinner table by 2050. If this prediction is correct, the world is going to need more crops, more livestock, and more efficient agricultural practices.
Landsat—The watchman that never sleeps
In western North America, where infestations of mountain pine beetles continue to ravage thousands of acres of forest lands, Landsat satellites bear witness to the onslaught in a way that neither humans nor most other satellites can see.Young, Steven
When wildfire damage threatens humans, Landsat provides answers
A wildfire’s devastation of forest and rangeland seldom ends when the last embers die. In the western United States, rain on a scorched mountainside can turn ash into mudslides. Debris flows unleashed by rainstorms can put nearby homes into harm’s way and send people scrambling for safety. The infrared capabilities of Landsat satellite imagery...Young, Steven
Mapping water use - Landsat and water resources in the United States
Using Landsat satellite data, scientists with the U.S. Geological Survey (USGS) have helped to refine a technique called evapotranspiration (ET) mapping to measure how much water crops are using across landscapes and through time. These water-use maps are created using a computer model that integrates Landsat and weather data. Crucial to the...Johnson, Rebecca L.
The global Landsat archive: Status, consolidation, and direction
New and previously unimaginable Landsat applications have been fostered by a policy change in 2008 that made analysis-ready Landsat data free and open access. Since 1972, Landsat has been collecting images of the Earth, with the early years of the program constrained by onboard satellite and ground systems, as well as limitations across the range...Wulder, Michael A.; White, Joanne C.; Loveland, Thomas; Woodcock, Curtis; Belward, Alan; Cohen, Warren B.; Fosnight, Eugene A.; Shaw, Jerad; Masek, Jeffery G.; Roy, David P.
