NoData value is not defined
Nikolaos,
I just tried:
gdalwarp utm.tif -dstnodata 255 out.tif
and the nodata value was set properly on out.tif with trunk, gdal-1.7 and
gdal-1.6. Is it possible that test.tif already existed when you ran the
gdalwarp command? It won't be recreated and some options might have no
effect when the output file already exists.
Best regards,
--
