[GRASS-user] Error with pansharpening

[Vishal Mehta]

Hi all,

I'm using GRASS 7.8 on WIndows 10, and trying out some of the Landsat
routines.

I'm getting an error on pan sharpening, at the very end of the processing:
and i see some temp files have been created. is there a way to fix this?
Thanks, Vishal
