Question About Landsat 8 Band 8 Processing in SCI

[pamelamol]

Hi Luca,

I would like to clarify a question regarding the processing of Landsat 8 data in SCI.

While performing the processing, I noticed that Band 8 (panchromatic) does not appear together with the other bands. Could you please explain why this band is not included in the processing?

Thank you!

Hi @pamelamol ,

the panchromatic band is not processed because it is not included in level 2 products, and in general it is not used for classifications.

Hi Luca,

Thank you for the clarification.

In my case, I am working with Landsat 8 LC08 1TP products, which already include geometric correction, but not atmospheric correction. In addition, these products contain the 15 m panchromatic band (Band 8).

When using SCI plugin version 7.10.11, the panchromatic band is processed if the option “Perform Pansharpening (Landsat 7 and 8)” is enabled. Because of this, I was wondering why Band 8 is not appearing in the current processing workflow.

Another Subject:
I also tried using a newer SCI version (8.5.0) to collect samples and generate the spectral signature plots. However, I encountered the following error message:

“Information [4]: Select a raster; raster is not loaded”

This error prevents the sample selection process, so I cannot continue from that point.

I checked some installation procedures shared on Facebook, but they were only for Mac systems. I am using Windows.

My current attempt to solve the issue was to completely uninstall QGIS, delete all QGIS-related folders, and then try using SCI version 7.10.11 instead.

Could this issue be caused by residual files or folders from previous installations?

Thank you again for your support.
