[Gdal-dev] SID to TIF

[Ed McNierney]

Dave -

The FAT32 filesystem has a file size limit of 4GB, and the popular Linux
filesystems (ext2, ext3, ReiserFS) have the same limitation for the
standard filesystem API (the Large File System interface in 2.4 kernels
requires apps written to the LFS API).  NTFS filesystems do not have a
4GB file limitation.

However, it's VERY common to see application software with 4GB file size
limits coded into it, but I would double-check with LizardTech before
concluding that the 4GB output file limit is due solely to Windows or is
a limitation of the MrSID software.

Subject: [Gdal-dev] SID to TIF

Are there any limitations to the size of TIF that can be created when
going from SID to TIF using GDAL compiled with the Lizardtech SDK? We
have been trying to decompress some color county mosaics using
mrsiddecode from Lizardtech without success and it has been suggested
that this is because there is a 4GB file size limit for the resultant
TIF - supposedly due to MS Windows - and our resultant TIF would be 8GB
or more. Does anyone know if this would apply to using GDAL on Windows?
What about GDAL on Linux? If all of these seem to be dead ends, has
anyone got any suggestions on decompressing these things?

 

Thanks,

 

Dave
