[gdal-dev] Listgeo -tfw trouble

[Jukka Rahkonen]

Hi,

I am trying to generate world files for GeoTIFF images with command
listgeo -tfw tfwtest.tif However, it leads to this error:
TIFFReadDirectory: Warning, Unknown field with tag 42113 (0xa481) encountered.

Tfwtest.tif is subsampled image done with gdal_translate from an original
written by gdal_warp. Image is in epsg:3067 projection (ETRS-TM35FIN). I tried
running listgeo from FWTools 1.3.6 and 2.0.6 versions. Listgeo works with some
other images. Any idea why listgeo does not like my images? Gdalinfo listing of
tfwtest.tif follows.
