Landsat 7 CPF Historical Change Log

By Landsat Missions

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. 

Return to Landsat 7 Calibration Notices Overview
 

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.
