EROS CalVal Center of Excellence (ECCOE)

Landsat Calibration and Validation

ECCOE maintains primary responsibility for radiometric and geometric characterization and Calibration of the Landsat instruments and spacecrafts.  This work includes both the ongoing operations of active Landsat missions, as well as the retired Landsat missions.

ECCOE supports Landsat with preflight instrument and spacecraft characterization and Calibration. This includes supporting upcoming missions such as Landsat 9.

Landsat Collection 2 marks the second major reprocessing effort on the Landsat archive by the USGS that results in several data product improvements that harness recent advancements in data processing, algorithm development, and data access and distribution capabilities.

A primary characteristic of Collection 2 is the substantial improvement in the absolute geolocation accuracy of the global ground reference dataset - which improves interoperability of the Landsat archive through time. Collection 2 also includes updated global digital elevation modeling sources and calibration and validation updates.


ECCOE maintains Landsat mission support data sets such as the Digital Elevation Model (DEM) and Ground Control Chips (GCP) Library needed for Level-1 product generation, along with Calibration and characterization support sites and datasets, such as Pseudo Invariant Calibration (PICS) sites and Modulation Transfer Function (MTF) bridge targets.
