Re: [Qgis-user] Pansharpening Problem

Hi Grant:

If you are ending up with null values and zero's, check the values in 
the raster you are pan sharpening against the training or higher 
resolution raster you are using to sharpen. Is there null data in the 
high res raster.  Review the input requirements of the routine to ensure 
the tool will work with your data. Perhaps pan sharpening a 3 channel 
raster with a single channel raster creates the problem.

gdal pansharpen tool and latest release QGIS 3.34.

[Qgis-user] Pansharpening Problem
