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.

MoD-FIS Brings Seasonal Fine Fuels Information to Wildland Fire Management

In roughly 50 percent of New Mexico, Arizona, and west Texas, wildfires that burn across hard-baked desert landscapes need annual/invasive herbaceous and other fine fuels to drive them.

Miglarese, Radiant Earth Advocate for Benefits of Open Training Datasets

Anne Hale Miglarese has a simple mantra when it comes to gathering and using training data for remote sensing.

Collect it once, the founder of the nonprofit Radiant Earth Foundation, says. Then use it many times.

A novel approach for next generation water use mapping using Landsat and Sentinel-2 satellite data

Evapotranspiration (ET) is needed in a range of applications in hydrology, climatology, ecology, and agriculture. Remote sensing-based estimation is the only viable and economical method for ET estimation over large areas. The current Landsat satellites provide images every 16 days limiting the ability to capture biophysical changes affecting...

Quantifying drought’s influence on moist soil seed vegetation in California’s Central Valley through remote sensing

Across the Central Valley of California, millions of wintering waterfowl rely on moist soil seed (MSS) plants that grow in managed seasonal wetlands as a critical source of food. Estimates of MSS plant production are used to set waterfowl habitat targets yet this information is not well known. We created the first Central Valley-wide time series...

Harmonizing the Landsat ground reference with the Sentinel-2 Global Reference Image using space-based bundle adjustment

There is an ever-increasing need to use accurate and consistent geometric ground reference in the processing of remotely sensed data products as it reduces the burden on the end-users to account for the differences between the data products from different missions. In this regard, United States Geological Survey (USGS) initiated an effort to...
