5. Radiometric Correction
In addition to distortions in image geometry, image radiometry is affected by factors, such as system noise, sensor malfunction and atmospheric interference. The purpose of radiometric calibration is to remove or reduce the sensor (detector) inconsistencies, sensor malfunction, viewing geometry and atmospheric effects. We will first introduce the calibration of detector responses.
5.1 Detector Response Calibration
5.2 Atmospheric Correction of Remotely Sensed Data
5.3 Topographic Correction
