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.

Image of the Week - New Rift on Greenland's Petermann Glacier
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.

Every Pixel - Recording Data
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.

Every Pixel - Ground Stations
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.

Every Pixel - Processing Data
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.

Majuro Atoll — Topobathymetric Model
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.

Image of the Week - Isle de Jean Charles, Louisiana
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.

Landsat Analysis Ready Data (ARD)
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.

Choosing a Data Access Tool: AppEEARS Area Sampler
This video focuses on the Application for Extracting and Exploring Analysis Ready Samples (AρρEEARS) Area Sampler. With AρρEEARS, users can retrieve analysis ready data for specific areas of interest for a variety of NASA data products, including those derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard NASA’s Terra and Aqua satellites.
