Re: [GRASS-dev] [EXTERNAL] Can GRASS import a *.ige file?

[Michael Barton via grass-dev]

The info I downloaded for 2021 had a much more modes sized *.img file and a 
huge *.ige file (25 Gb or so). It looks like the best approach is to use the 
*.img file and discard the *.ige file. Perhaps that latter is the uncompressed 
one.

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!

Any suggestions on how to get this into the raster? Or are you thinking we

Re: [GRASS-dev] [EXTERNAL] Can GRASS import a *.ige file?

[Newcomb, Doug via grass-dev]

No,
The .ige file is what spills over after the 4GB of the .img file fills up.  You 
need to have both.
