EROS CalVal Center of Excellence (ECCOE)
Home
Leveraging years of multi-scale optical system geometric and radiometric calibration and characterization experience, 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:
| ECCOE maintains the 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. | Requirements Capabilities & Analysis for Earth Observations (RCA-EO) works to understand user needs for Earth observation, measurement, and monitoring. |
| MORE INFORMATION | MORE INFORMATION | MORE INFORMATION |
| Lidar data and their derivative metrics are fundamental inputs to many areas of scientific research, including flood, erosion, and coastal modeling. | Unmanned 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. |

New Edition of JACIE Remote Sensing Compendium Released for 2020
The USGS Earth Resources Observation and Science (EROS) Center and its Joint Agency Commercial Imagery Evaluation (JACIE) partners have just released the second edition of the JACIE land remote sensing satellite compendium.
Lunar Calibration with Landsat
The next full moon will come on September 2, 2020. And when you look up to see it, so will Landsat 8. As probably the most accurate Earth imaging satellite system, Landsat has multiple ways of calibrating data to ensure its accuracy and interoperability with other satellites. One of the strategies the calibration engineers use is lunar calibration.
Calibration Test Site Becomes Agricultural Hotspot
The Landsat satellites were designed to detect landscape changes over time. However, sometimes what Landsat needs to see on the Earth’s surface is no change at all.

Landsat collection 2
Landsat Collections ensure that all Landsat Level-1 data are consistently calibrated and processed and retain traceability of data quality provenance. Landsat Collection 2 introduces improvements that harness recent advancements in data processing, algorithm development, data access, and distribution capabilities. Collection 2 includes Landsat...
The new Landsat Collection-2 Digital Elevation Model
The Landsat Collection-2 distribution introduces a new global Digital Elevation Model (DEM) for scene orthorectification. The new global DEM is a composite of the latest and most accurate freely available DEM sources and will include reprocessed Shuttle Radar Topographic Mission (SRTM) data (called NASADEM), high-resolution stereo optical data (...
Franks, Shannon; Storey, James C.; Rengarajan, Rajagopalan Harmonizing the Landsat ground reference with the Sentinel-2 Global Reference Image using space-based bundle adjustment
There is an ever-increasing need to use accurate and consistent geometric ground reference in the processing of remotely sensed data products as it reduces the burden on the end-users to account for the differences between the data products from different missions. In this regard, United States Geological Survey (USGS) initiated an effort to...
