When parking lots go up, when rooftops multiply, land cover and land uses change. Professor Andrew Elmore with the University of Maryland’s Center for Environmental Science understands that very well, and explains how he uses Landsat to study and quantify that change in USGS EROS’ latest “Landsat in Action” video conversation. Elmore delves into the changing phenology of forests and how that...
A new rift is forming across the Petermann Glacier. If this rift connects to existing rifts, it could result in another large iceberg breaking free.
At the USGS EROS Center, we study land change, operate the Landsat satellites, and maintain the longest, continuously acquired collection of images of the Earth's land surface.

Once the ground stations receive data from Landsat, there's still a lot of processing to make every pixel usable. Here's an overview of some of that work.
Every pixel of Landsat data is transmitted down to a network of ground stations around the world. Here is an overview of how that happens.
Recording every pixel as Landsat orbits Earth is a complicated task. Here is an overview of how that data goes from the sensors into the recorder.
On board Landsat 8 are two sensors that capture data about earth's surface. Here is an explanation of the instruments that capture every pixel.
Ever wonder how Landsat 8 orbits our planet? Here is an overview to explain this part of how we capture every pixel.
A tour of the Planetary Geologic Mapping Python toolbox, a suite of GIS tools from the Astrogeology Science Center.
Geoscience Australia's Acting Chief Scientist Adam Lewis talks about the value of Landsat data, the importance of free and open policy, and how analysis ready data is advancing earth observing science.
This video is of is a three-dimensional (3D) view of the Majuro Atoll, Republic of the Marshall Islands topobathymetric model which consists of topography (land elevation) and bathymetry (water depth). This video shows the importance of high-resolution, detailed topobathymetric models because the highest natural elevation for the Majuro Atoll is only three meters. This video shows how the...
- Sea otters are perhaps the best-known example of a "keystone predator".
- Sea otter behavior -- in particular diet specialization and limited mobility -- can mediate their effects on ecosystem dynamics.
- Other predators, especially large sea stars, can complement and reinforce the keystone role of sea otters: this became apparent with the loss of all sea stars from wasting ...
The imagery featured in this video was created using data distributed by the National Aeronautics and Space Administration’s (NASA) Land Processes Distributed Active Archive Center (LP DAAC). These satellite-derived data are from NASA’s Making Earth System Data Records for Use in Research Environments (MEaSUREs) Global Food Security-support Analysis Data (GFSAD) Cropland Extent data product (...
A USGS video about manatees reveals that while the animals may act like the cows of the sea, they also have more than a bit of the magical siren or mermaid about them. Go for a serene swim.
A team of USGS scientists spent two weeks in the isolated Glacier Bay National Park, exploring one of the fastest-moving faults in North America.
Lesson 3a: The National Map Viewer Interface and Data Content. In this lesson, we will provide the user with an overview and demonstration of the interface and data content of The National Map Viewer.
Lesson 3b: The National Map Viewer Tool Functionality: Legend, Measure, Elevation Profile, and Spot Elevations. In this lesson, we will provide the user with a demonstration of functionality and capabilities of tools in The National Map Viewer.
Off the coast of Louisiana, the small Isle de Jean Charles has nearly been swallowed by the ocean. Only about 2% of the land mass remains compared to it's size in the 1950s.
The U.S. Geological Survey (USGS) has improved Landsat data quality and usability through the creation of Analysis Ready Data (ARD) for the conterminous United States, Alaska, and Hawaii. Landsat ARD greatly reduces the preparatory work currently required to do time-series analysis for understanding landscape change for operational and science users. Landsat Collections Level-1 scenes are the...
LGSOWG #46 was held in Rapid City, South Dakota in 2017.
Out with the old, in with the new! A state-of-the-art aquatic science laboratory is being built on the shores of Lake Huron at the USGS Hammond Bay Biological Station (HBBS), one of seven field stations of the USGS Great Lakes Science Center, operated in partnership with the Great Lakes Fishery Commission. To make way for the new laboratory, four old buildings on the HBBS property needed to be...
Lesson 9a: Accessing US Topo Through the USGS Store. This lesson will cover how to access the USGS Store and where to download free USGS Topo maps.
- The U.S. is increasingly reliant on supply of mineral raw materials from other countries.
- Advanced technologies are increasingly making use of nearly the entire periodic table of the elements.
- Dynamic studies of critical and strategic mineral supply and demand can identify emerging potential supply risks.
- The USGS - National Minerals Information Center has ...
