USGS EROS Center

USGS EROS Center
Name	Earth Resources Observation and Science Center
Established	1973
Location	Sioux Falls, South Dakota, United States
Parent organization	United States Geological Survey

USGS EROS Center is a federal research and data facility focused on remote sensing, satellite imagery, and geospatial analysis. Located near Sioux Falls, South Dakota, it serves as a national archive and processing hub for Earth observation data used by agencies such as the National Aeronautics and Space Administration, the National Oceanic and Atmospheric Administration, the Department of the Interior, and international partners. The center supports scientific programs involving instruments on platforms like Landsat, Sentinel-2, and commercial constellations, enabling applications across fields including climate change, natural disaster response, and land use planning.

History

The center traces roots to early efforts in satellite remote sensing in the 1960s and the development of programs by National Aeronautics and Space Administration initiatives such as the Landsat program and collaborations with the U.S. Geological Survey. Established formally in the 1970s amid expansion of the Landsat archive, the facility evolved alongside milestones including the launch of Landsat 1, the passage of policies influenced by the National Earthquake Hazards Reduction Program, and shifts in federal data management influenced by legislation like the Paperwork Reduction Act. Over decades, modernization efforts incorporated partnerships with entities such as the National Geospatial-Intelligence Agency, research funded by the National Science Foundation, and collaborations with academic institutions including University of California, Santa Barbara and University of Maryland. Milestones include transitions to digital archives, adoption of cloud-based dissemination models concurrent with initiatives from Google and cloud providers, and responses to events such as major floods, wildfires, and hurricanes documented alongside work by FEMA.

Mission and Functions

The center's mission aligns with mandates of the United States Geological Survey to collect, archive, and distribute Earth observation data supporting science and public policy. Core functions include long-term stewardship of satellite archives like Landsat 4 through Landsat 9, operational processing of imagery for programs linked to the Global Land Cover Facility, and provision of calibrated, orthorectified products used by agencies including the Environmental Protection Agency and the Department of Agriculture. The facility supports downstream applications in hydrology research tied to the U.S. Army Corps of Engineers, wildfire monitoring used by the U.S. Forest Service, and analysis required for international reporting frameworks such as the Intergovernmental Panel on Climate Change.

Facilities and Infrastructure

Situated on a secure campus in Sioux Falls, South Dakota, the center houses high-performance computing clusters, mass storage systems, and archival media arrays comparable to infrastructure deployed by the National Center for Supercomputing Applications and the Oak Ridge National Laboratory. Onsite laboratories support radiometric calibration, instrument testing, and image processing workflows similar to those at NASA Goddard Space Flight Center. The center maintains redundant power, climate-controlled vaults for long-term tape archives, and high-bandwidth network connections to national research and education networks like Internet2 and ESnet to enable data transfer to users including the University of Colorado Boulder and international science organizations.

Data Collections and Services

The facility curates multi-decadal collections comprising optical, thermal, and radar datasets from missions such as Landsat, Sentinel-1, Sentinel-2, and historical aerial photography projects linked to the National Agricultural Imagery Program. Services include online search and download portals, bulk data access, and APIs enabling integration with platforms developed by Google Earth Engine, Esri, and research groups at Massachusetts Institute of Technology. Products encompass surface reflectance, top-of-atmosphere radiance, and analysis-ready data consumed by agencies including the National Park Service, U.S. Fish and Wildlife Service, and international partners such as the European Space Agency.

Research and Applications

Research programs leverage data to study land-change science, carbon fluxes, urban growth, and disaster impacts, interfacing with research centers at institutions like Columbia University, Stanford University, and Pennsylvania State University. Applied projects include national-scale mapping for the U.S. Census Bureau and cropland monitoring for the U.S. Department of Agriculture's programs, as well as hazard assessment models used by NOAA and FEMA. Peer-reviewed collaborations have resulted in publications in journals such as Science, Nature, and Remote Sensing of Environment addressing topics from deforestation in the Amazon to permafrost thaw in the Arctic linked to studies by the National Snow and Ice Data Center.

Partnerships and Collaborations

The center partners with federal agencies including NASA, NOAA, the National Geospatial-Intelligence Agency, and the Department of Agriculture; academic partners such as University of California, Berkeley and Johns Hopkins University; state agencies; and international organizations like the European Space Agency and the Group on Earth Observations. Collaborations enable interoperability with standards from the Open Geospatial Consortium and contribute to multi-agency initiatives such as the Committee on Earth Observation Satellites and the U.S. Group on Earth Observations for global data sharing and capacity building.

Public Access and Outreach

Public access programs provide educators, researchers, and the public with tools and training coordinated with outreach partners such as the Smithsonian Institution, state historical societies, and university extension services. Educational initiatives include workshops, webinars, and data challenges in cooperation with organizations like National Science Teachers Association and citizen science efforts aligned with Zooniverse. Outreach emphasizes open data principles promoted by the Office of Management and Budget and supports applications in environmental stewardship used by local governments, non-governmental organizations such as The Nature Conservancy, and community planners.
