Hi all,
I think this might be a libtiff issue, but I'll cross post it here as
well just in case.
The issue I'm having is processing a 2.7 gb single page tiff. I wanted
to use gdal_retile (tried gdal 1.7.0b2 and 1.8.0) on this to first tile
and then eventually pyramid the resultant images.
However, when I tried to do a gdalinfo command or gdal _retile command
on the image I'd just get a memory error. So I tried to make the tiff
smaller using gdal_translate but got the same error:
gdal_translate -outsize 50% 50% \gebco_nordic_mareano_utm33.tif
c:\gebco50.tif
ERROR 1: \gebco_nordic_mareano_utm33.tif:Failed to allocate memory for
to read TIFF directory (0 elements of 12 bytes each)
ERROR 1: TIFFReadDirectory:Failed to read directory at offset 29368

I have built using the bigtiff option so the size shouldn't be an issue,
does anyone have any thoughts on this, I've just come up against a brick
wall!!
Cheers
