Hi, I am trying to perform a radiometric calibration of an Aster image on ENVI, I watched a youtube tutorial where they use the Radiometric calibration tool, but when I tried to do it on my computer the Radiometric Calibration tool is not displayed, does anyone has an idea of why, I already restarted either the program and the computer but it seems it's not helping.

Hi ,
There are a few reasons why the Radiometric Calibration tool might not be displaying in ENVI. Here are a few things to check:
- Make sure that you have the latest version of ENVI installed. The Radiometric Calibration tool was added in ENVI 5.3, so if you are running an older version, the tool will not be available.
- Make sure that the image you are trying to calibrate is a supported format. The Radiometric Calibration tool only works with certain types of images, such as Landsat, Sentinel-2, and Aster.
- Make sure that the image you are trying to calibrate has the correct metadata. The Radiometric Calibration tool needs to know the gain and offset values for each band in the image in order to perform the calibration.
- If you have checked all of these things and the Radiometric Calibration tool is still not displaying, you can try contacting ENVI support for help.
Here are some additional troubleshooting tips:
- Try opening the image in a different image viewer to see if the metadata is correct.
- Try exporting the image to a different format and then opening it in ENVI.
- Try reinstalling ENVI.
I hope this helps !
Please recommend my reply if you find it useful .Thanks

Set the correct gain and offset for all bands in the attribute information of the image
