Fix the calibration for a NOAA-14 image.
Fix the calibration for a NOAA-14 image. Since calibration has been improperly applied to some NOAA-14 images, this routine is used to "back-out" the calibration and to re-apply the calibration correctly. The input LAS image is updated by this routine.
- IN
- Input image. IN may be a single- or multi-band image and may contain BYTE or INTEGER*2 pixel data. Only one band of data may specified, windowing may not be specified.
- CHANNEL
- Channel number. AVHRR channel number coinciding with the band specified by IN.
The user has requested to re-apply calibration to the third band of LAS image "NY.DAT". This band of data is from the AVHRR channel 3. Only band 3 will be updated.
A line of the specified input band is read. For each sample, the improperly applied calibration is accounted for, and calibration is applied correctly. The line of data is then updated in the input image. Processing continues until each line of the input band has been updated.
A nonfatal error was encountered during processing. The image data is probably valid and therefore saved. The error message that is displayed immediately preceding this message is the specific error that was encountered. Processing continues.
A fatal error was encountered during processing. Processing is terminated. The error message that is displayed immediately preceding this message is the specific error that was encountered.
