You can't stack them if they're from different extents but depending on how huge this dataset is perhaps you could stitch the rasters together? Your working directory shouldn't change in a loop, what you want to change is the path variable. I'll edit to clarify. | |

However, in my case I am dealing with hundreds of images that have different extents therefore i can not stack them if I am correct. Furthermore, they are in different directories - this is the reason i am setting the directory within the loop. That was the only way i knew how to import these rasters from different directories, and this also allowed me to take the raster names and put them in columns of the dataframe for the further usage. | |
