Earth Resources Observation and Science (EROS) Center

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
Our second set of interviews from the Landsat 9 launch includes conversations with international partners and Landsat users on the critical value of the program’s continuity.

Water levels in Lake Powell, which supplies water to millions in the southwestern U.S., hit historic lows in 2021. Comparing Landsat imagery from 2017 and 2021 highlights the dramatic difference.

Landsat 9 Serves as Backbone of Efforts to Reduce Deforestation and Forest Degradation
The Landsat program has long been a powerful partner in the effort to manage and reduce carbon emissions worldwide.
The launch of Landsat 9 and its extension of the program’s nearly 50-year record of Earth surface change will help ensure the stability of those efforts, according to officials working with developing nations to monitor deforestation and forest degradation.
LCMAP Adds Data for 2020 with Release of Collection 1.2
The USGS Land Change Monitoring, Assessment, and Projection (LCMAP) initiative has released the second update to its Conterminous United States (CONUS) science products, adding the most recent calendar year of data to an unparalleled annual land cover and land surface change time series that stretches back to 1985.
Underfly Positions Landsat 9 Below Landsat 8 for Simultaneous Scenes
The newly launched Landsat 9 is experiencing a once-in-a-mission lifetime event where its orbit is directly below Landsat 8 for an “underfly.” For several days in the middle of November, the pair of Earth-observing satellites are flying together, collecting data at the same time for the same sites and requiring simultaneous downlinking to global ground station antennas.
