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: 

Landsat-JACIE-RCAEO-image

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-UAS-TSC-image

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.

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.

2020 Joint Agency Commercial Imagery Evaluation—Remote sensing satellite compendium

The Joint Agency Commercial Imagery Evaluation (JACIE) is a collaboration between five Federal agencies that are major users and producers of satellite land remote sensing data. In recent years, the JACIE group has observed ever-increasing numbers of remote sensing satellites being launched. This rapidly growing wave of new systems creates a need...

General external uncertainty models of three-plane intersection point for 3D absolute accuracy assessment of lidar point cloud

The traditional practice to assess accuracy in lidar data involves calculating RMSEz (root mean square error of the vertical component). Accuracy assessment of lidar point clouds in full 3D (dimension) is not routinely performed. The main challenge in assessing accuracy in full 3D is how to identify a conjugate point of a ground-surveyed...

Bundle adjustment using space based triangulation method for improving the Landsat global ground reference

There is an ever-increasing interest and need for accurate geo-registration of remotely sensed data products to a common global geometric reference. Although the geo-registration has improved significantly in the last decade, the lack of an accurate global ground reference dataset poses serious issues for data providers seeking to make...
