Landsat 7 CPF Historical Change Log

Calibration and validation are important aspects of any remote sensing system. The calibration of the Landsat sensors is supported by preflight, post launch-onboard, and ground reference data. Calibration Parameter files (CPF) provide radiometric and geometric coefficients needed for processing of raw, uncorrected Landsat image data. 

Each timeframe specific CPF contains calibration coefficients that have been adjusted to correct for the time varying performance of the sensor.

NOTE: This page contains information back to January 2018. For previous logs, visit this page

Visit the Landsat Calibration/Validation CPF page to learn more about calibration parameter files.
