Hi,
I am rather sure that everything is OK and warning you get means just what it
tells: there is some tiff tag not recognised by tiffinfo.

Hi,
I have sucessfully converted the ESRI ascii grid file to Geotiff using
gdal_translate. But using tiffinfo on newly created file gives me something
like this:
TIFFReadDirectory: Warning, Unknown field with tag 33550 (0x830e)
encountered.
TIFFReadDirectory: Warning, Unknown field with tag 33922 (0x8482)
encountered.
TIFFReadDirectory: Warning, Unknown field with tag 42113 (0xa481)
encountered.

The file is displayed correctly but when I try to build the overviews
using gdaladdo I get warnings:
Warning 1: TIFFReadDirectory:LDAY.tif: Wrong "StripByteCounts" field,
ignoring and calculating from imagelength
Warning 1: TIFFReadDirectory:LDAY.tif: Wrong "StripByteCounts" field,
ignoring and calculating from imagelength
New file with overviews is created and everything looks fine with
gdalinfo, but tiffinfo gives the same output as before. Is this something I
need to care about or I can just ignore it?
regards, dejan
