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-Supported Projects

ECCOE Staff provide technical support to a number of USGS projects that are important in Earth Observation discovery and data characterization: 

Landsat, JACIE, Satellites Compendium
ECCOE maintains primary responsibility for radiometric and geometric characterization and calibration of the Landsat instruments and spacecrafts. The Joint Agency Commercial Imagery Evaluation (JACIE) team assesses the quality and capabilities of newly launched commercial high-resolution satellites. The Land Remote Satellites Online Compendium contains details about past, present and future Earth observing satellites and the sensors they carry.

lidar,uas,test site catalog images
Lidar data and their derivative metrics are fundamental inputs to many areas of scientific research,  including flood, erosion, and coastal modeling. Uncrewed Aerial Systems (UAS) allow for new opportunities for gathering data essential to land management and Earth science. The Test Site Catalog Contains worldwide calibration sites used for post launch characterization and calibration of space-based optical imaging sensors.

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

Evaluation of Copernicus DEM and comparison to the DEM used for Landsat collection-2 processing

Having highly accurate and reliable Digital Elevation Models (DEMs) of the Earth’s surface is critical to orthorectify Landsat imagery. Without such accuracy, pixel locations reported in the data are difficult to assure as accurate, especially in more mountainous landscapes, where the orthorectification process is the most challenging. To this end, the Landsat Calibration and Validation Team (Cal/
