WebbThis task applies custom gain and offset values to each band of a raster, updating the pixel values accordingly. The output raster can be used for a custom calibration routine. This task is different from the RadiometricCalibration task, which applies gains and offsets automatically to common data types such as Worldview and Landsat.
