Earth Resources Observation and Science (EROS) Center
Home
At the USGS EROS Center, we study land change and produce land change data products used by researchers, resource managers, and policy makers across the nation and around the world. We also operate the Landsat satellite program with NASA, and maintain the largest civilian collection of images of the Earth’s land surface in existence, including tens of millions of satellite images.
Eyes on Earth
Episode 47 of our Eyes on Earth podcast is a conversation with one of the founders of Ladies of Landsat, a group working to expand diversity and inclusion in the field of remote sensing.

The Bay of Fundy in Canada has a unique geography funneling the Atlantic Ocean into some of the world's highest tides. The stunning tidal movement can be simulated by resequencing Landsat imagery.

New York Tries Creative Ways—Like Satellites—to Fight Hemlock-Killing Insect
Hunting for an insect the size of a poppy seed in a forest of trees that can soar 100 feet high is, admittedly, a tall task.
But after seeing the “gray ghosts” of dead eastern hemlock trees haunt forests farther south, officials in New York have been intent on preventing the same fate for the state’s eastern hemlocks as the aphid-like hemlock woolly adelgid (HWA) creeps north.
Ladies of Landsat Group Offers Sense of Belonging and Support
Finding connections and a sense of community help make work more fulfilling. But a feeling of belonging can be harder for some people to find than others. A remote-sensing-focused Twitter group is trying to do something about that.
New EROS Tool Shows County-By-County Change Across United States
The USGS Earth Resources Observation and Science (EROS) Center has released a new online tool to help the public better visualize county-by-county land change across the United States.

Oregon and Landsat
Oregon’s landscape is as complex and diverse as it is beautiful. Mountain peaks in the Cascade Range soar higher than 10,000 feet. Crater Lake sinks to a depth of 1,943 feet, making it the deepest lake in the United States. Oregon’s lands feature forests, farm fields, grasslands, ocean coastline, rivers, a semidesert, and mountain ranges that...
The effects of urban land cover dynamics on urban heat Island intensity and temporal trends
Assessments of surface urban heat island (UHI) have focused on using remote sensing and land cover data to quantify UHI intensity and spatial distribution within a certain time period by including land cover information. In this study, we implemented a prototype approach to characterize the spatiotemporal variations of UHI using time series of...
Xian, George Z.; Shi, Hua; Auch, Roger F.; Gallo, Kevin; Zhou, Qiang; Wu, Zhuoting; Kolian, Michael Exploring the regional dynamics of U.S. irrigated agriculture from 2002 to 2017
The United States has a geographically mature and stable land use and land cover system including land used as irrigated cropland; however, changes in irrigation land use frequently occur related to various drivers. We applied a consistent methodology at a 250 m spatial resolution across the lower 48 states to map and estimate irrigation dynamics...
