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.
What's New at EROS?
The USGS has developed research-quality, applications-ready, Landsat Level-3 Science Products that are now available for download.Full story

With a vegetation and fuels base map that was over 15 years old and a commitment to keep LANDFIRE (LF) data relevant, LF staff at EROS has produced a new base map product suite, representing 2016 ground conditions.
The case for sagebrush habitat as the iconic landscape of the American West is a fairly one easy to make.
Validating a time series of annual grass percent cover in the sagebrush ecosystem
We mapped yearly (2000–2016) estimates of annual grass percent cover for much of the sagebrush ecosystem of the western United States using remotely sensed, climate, and geophysical data in regression-tree models. Annual grasses senesce and cure by early summer and then become beds of fine fuel that easily ignite and spread fire...Boyte, Stephen P.; Wylie, Bruce K.; Major, Donald J.
Landsat: The cornerstone of global land imaging
Since 1972, the joint NASA/ U.S. Geological Survey Landsat series of Earth Observation satellites have provided an uninterrupted space-based data record of the Earth’s land surface to help advance scientific research towards the understanding of our planet and the environmental impact of its inhabitants. Early Landsat satellites offered a wealth...Butcher, Ginger; Barnes, Christopher; Owen, Linda
Linking landscapes and people—Projecting the future of the Great Plains
We developed a unique set of landscape projections for the Great Plains that use real land-management parcels to represent landscape patterns at high spatial and thematic resolution.Both anthropogenic land use and natural vegetation respond in the model to projected changes in groundwater availability and climate...Sohl, Terry L.; Dornbierer, Jordan; Wika, Steve
