[gdal-dev] Using GDAL with KOMPSAT-2 images

[Luis Lisboa]

Greetings

While I was importing to GRASS some KOMPSAT-2 images I got a few warnings.
Then, I decided to do some GDALINFO over those Kompsat-2 images and I got
the following warnings:

Warning 1: TIFFFetchNormalTag:ASCII value for tag "DocumentName" does not
end in null byte
Warning 1: TIFFFetchNormalTag:ASCII value for tag "ImageDescription" does
not end in null byte
Warning 1: TIFFFetchNormalTag:ASCII value for tag "Artist" does not end in
null byte
Warning 1: TIFFFetchNormalTag:ASCII value for tag "HostComputer" does not
end in null byte

And only after this I got the gdalinfo response:

What this warnings refer to? is this a critical issue?

Thanks
