Michael, The last time I checked, the NLCD data in .img format is an uncompressed raster. You can save a massive amount of hard drive space by converting the .img files to deflate compressed geotiff, then linking via r.external.
That's what I did for the 2019 NLCD , https://youtu.be/0NHdWSF96o0 . The 2021 is the same. The .img /ige file is 26 GB for 1 year nationwide. Converting to deflate compressed geotiff takes it down to 1.5 GB. Hope this helps!

While it opens fine and is classified, there are no text labels for the landcover categories. Would these be hiding in the *.ige file? Michael _____________________________ C.
