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. |

| 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 Report Explains Landsat’s Role as ‘Gold Standard’ for Calibration
Landsat data have long been recognized for the quality and reliability of their calibration. A recent report puts a spotlight on that commitment to accuracy.
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.
