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. 
	TIFF Directory at offset 0x900008 (9437192)

	  Subfile Type: reduced-resolution image (1 = 0x1) 
	  Image Width: 714 Image Length: 714 
	  Tile Width: 128 Tile Length: 128

	  Compression Scheme: None 
	  Photometric Interpretation: min-is-black 
	  Samples/Pixel: 1 
	  Planar Configuration: single image plane 
	
	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
