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 

landsat 7 artist rendering over earth

 

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. 

Visit the Landsat Calibration and Validation webpage to learn more. 

 

 

Joint Agency Commercial Imagery Evaluation (JACIE)

JACIE image

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.

Earth Observing Satellites Online Compendium

The 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 EROS Center in Sioux Falls, South Dakota.

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

Three-dimensional (3D) data capture technologies continue to become more commonplace, as Uncrewed Aerial Systems (UAS) have become available. 

UAS's 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

Test Sites Catalog July 2021

 

The USGS ECCOE Test Sites Catalog began in 2007 to provide information about effective radiometric, geometric, and spatial qualities useful in the calibration of Earth observation sensors. The catalog now contains prime candidate test sites worldwide 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. 

Accurate, well-documented calibration is needed to understand and address local and global science and societal impacts and benefits.

Landsat Next

Landsat Next's launch in the early 2030s will ensure continuity of the longest space-based record of Earth’s land surfaces. The mission will substantially increase the breadth and quality of Earth observation data available to scientists, land managers, and others responsible for managing Earth's natural resources. Landsat Next’s constellation of three satellites will carry sensors that improve bo

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
