EROS CalVal Center of Excellence (ECCOE)

The EROS Cal/Val Center of Excellence (ECCOE) is a global leader in improving the accuracy, precision, and quality of remote sensing data. ECCOE experts provide support to Landsat Calibration/Validation, Uncrewed Aircraft Systems, Lidar-3DEP, and Satellite Derived Bathymetry activities. 

Landsat Calibration and Validation

The USGS ECCOE Landsat Cal/Val Team, along with their NASA counterparts, maintains primary responsibility for radiometric and geometric characterization and the calibration and validation of the Landsat instruments and spacecrafts. This work includes both the ongoing operations of active Landsat missions, as well as the retired Landsat missions.

Joint Agency Commercial Imagery Evaluation (JACIE)

The Joint Agency Commercial Imagery Evaluation (JACIE) was formed to leverage resources from several Federal agencies for the characterization of remote sensing data and to share those results across the remote sensing community.  Consisting of representatives from six Federal agencies, JACIE provides independent characterizations of image and image-derived end products. JACIE is the strong collaboration and enhanced working relationships between government and non-governmental organizations to understand remote sensing information and make it more useful to the user community. JACIE Workshops are held each year. Visit the JACIE page to learn more. 

 

Earth Observing Satellites Online Compendium

Screenshot of the Earth Observing Satellites Online Compendium

The Joint Agency Commercial Imagery Evaluation (JACIE) Earth Observing Satellites Online Compendium contains details about past, present and future Earth observing satellites and the sensors they carry.  

Derived from print versions of Compendiums published in 20192020, and 2022, this resource has been developed and is managed by the Requirements, Capabilities and Analysis for Earth Observation (RCA-EO) team at the USGS Earth Resources Observation and Science (EROS) Center in Sioux Falls, South Dakota.

Lidar

Lidar data and their derivative metrics are fundamental inputs to many areas of scientific research,  including flood, erosion, and coastal modeling and mapping, fault detection, land-surface mapping, landslide and volcano hazards, and mapping forest canopy.

Uncrewed Aerial Systems

Uncrewed Aerial Systems (UAS) allow for new opportunities for gathering data essential to land management and Earth science.  The potential of these systems requires that they be able to reliably gather accurate data.

Test Sites Catalog July 2021

Test Site Catalog

The Test Site Catalog contains prime candidate worldwide test sites for the calibration and post-launch characterization of space-based optical imaging sensors. The number of Earth-observing sensors and their derived science products continue to grow rapidly. Without characterization and calibration of these sensors, the products they provide could not be reliably used by scientists and decision makers. Accurate, well-documented calibration is needed to understand and address local and global science and societal impacts and benefits.

Need and vision for global medium-resolution Landsat and Sentinel-2 data products

Global changes in climate and land use are threatening natural ecosystems, biodiversity, and the ecosystem services people rely on. This is why it is necessary to track and monitor spatiotemporal change at a level of detail that can inform science, management, and policy development. The current constellation of multiple Landsat and Sentinel-2 satellites collecting imagery at predominantly ≤30-m s

The 50-year Landsat collection 2 archive

The Landsat global consolidated data archive now exceeds 50 years. In recognition of the need for consistently processed data across the Landsat satellite series, the U.S. Geological Survey (USGS) initiated collection-based processing of the entire archive that was processed as Collection 1 in 2016. In preparation for the data from the now successfully launched Landsat 9, the USGS reprocessed the

Guidelines for calibration of uncrewed aircraft systems imagery

Executive SummaryThis report outlines quality assurance (QA) processes, including radiometric and geometric calibration guidelines, and guidelines for data acquisition and quality control to be followed by U.S. Geological Survey (USGS) researchers for acquiring and processing uncrewed aircraft systems (UAS) data. These QA processes ensure that UAS data can be used for quantitative analysis and are
