USGS Earth Resources Observation and Science (EROS) Center is a remote sensing and geospatial data center that archives, processes, and distributes earth observation data for scientific, resource management, and policy applications. Located near Sioux Falls, South Dakota, it serves as a primary data repository and distribution hub within the United States Geological Survey network, supporting national and international users with satellite imagery, aerial photography, and derived geospatial products. The center underpins activities across NASA, National Oceanic and Atmospheric Administration, Environmental Protection Agency, Department of the Interior, and many academic and international partners.

Overview

EROS functions as a large-scale data archive and processing center, maintaining collections from satellites such as Landsat program, Sentinel-2, and historical aerial imagery from National Agriculture Imagery Program. It provides access to datasets used by stakeholders including United States Forest Service, Bureau of Land Management, National Park Service, and university researchers at institutions like Stanford University, Massachusetts Institute of Technology, and University of California, Berkeley. The center hosts computing resources, data stewardship personnel, and distribution systems that interface with platforms such as Amazon Web Services and initiatives tied to Group on Earth Observations and the Committee on Earth Observation Satellites.

History and Development

EROS traces its origins to early remote sensing and aerial photography programs managed under the United States Department of the Interior and later consolidated within the United States Geological Survey in the 20th century alongside projects like the Landsat 1 mission. Developments in the 1970s and 1980s paralleled milestones such as the establishment of the Earth Resources Technology Satellite program and collaborations with National Aeronautics and Space Administration on sensor calibration and data distribution. Over subsequent decades, EROS expanded its holdings through acquisitions of archives from agencies including the Defense Mapping Agency and partnerships with academic repositories at University of Maryland, College Park and University of Arizona. Modernization efforts coincided with federal initiatives such as the Geospatial Data Act of 2018 and investments in digital infrastructure inspired by programs like the DigitalGlobe commercial imagery services.

Facilities and Infrastructure

The EROS campus near Sioux Falls, South Dakota comprises secure archival vaults, data processing centers, and visitor facilities, co-located with South Dakota School of Mines and Technology research interactions. Its infrastructure includes high-capacity storage arrays, high-performance computing clusters influenced by designs used at National Center for Supercomputing Applications and networking connectivity to backbone providers similar to Internet2 and National Science Foundation facilities. The center operates satellite ground station interfaces and data ingest pipelines compatible with platforms such as Earth Observing System architectures and adheres to standards set by International Organization for Standardization and the Open Geospatial Consortium.

Data Collection and Products

EROS curates multi-decadal collections including the full archive of Landsat imagery, historical aerial photography, and thematic products like land cover maps used in assessments by Intergovernmental Panel on Climate Change, United Nations Environment Programme, and Food and Agriculture Organization. Product suites include surface reflectance, terrain models interoperable with United States Geological Survey National Map, and time-series analyses employed by researchers at Columbia University and Princeton University. Data distribution mechanisms incorporate web services compatible with Geographic Information System software from vendors such as Esri, open-source tools like QGIS, and cloud-hosted catalogs mirroring practices of Google Earth Engine.

Research and Programs

EROS supports research in land-use change, water resources, carbon accounting, and disaster response, collaborating with programs such as National Land Imaging Program, Landsat Science Team, and international efforts including Group on Earth Observations Land Cover activities. Research outputs inform policy and operational products used by Federal Emergency Management Agency for disaster mapping, United States Department of Agriculture for crop monitoring, and conservation projects with organizations like The Nature Conservancy and World Wildlife Fund. Scientific staff publish and contribute to studies affiliated with centers at NASA Goddard Space Flight Center, Jet Propulsion Laboratory, and academic groups at University of Minnesota and University of Colorado Boulder.

Partnerships and Collaborations

EROS maintains formal and informal partnerships with agencies and institutions including NASA, National Oceanic and Atmospheric Administration, United States Forest Service, Bureau of Land Management, and international space agencies such as European Space Agency, Canadian Space Agency, and Japanese Aerospace Exploration Agency. Collaborations extend to commercial entities like Maxar Technologies and research consortia such as Consortium for the Advancement of Remote Sensing and university networks including Iowa State University and University of Wisconsin–Madison. Through memoranda and joint projects, EROS contributes to multinational programs like Global Earth Observation System of Systems and capacity-building with partners including United Nations agencies and regional bodies.

Outreach and Education

The center conducts outreach and training for federal, state, tribal, and international audiences, offering workshops used by personnel from South Dakota State University, National Interagency Fire Center, and tribal nations. Educational resources support curricula at schools and universities, internships tied to programs like the American Geophysical Union student initiatives, and public engagement through exhibits that align with museums such as the Smithsonian Institution and science centers including the Museum of Science and Industry (Chicago). EROS also provides tools and documentation for citizen science and community mapping projects coordinated with organizations like OpenStreetMap Foundation and non-profits focused on environmental monitoring.
