[gdal-dev] gdal_translate alters NITF's metadata

Fri Apr 20 12:20:59 EDT 2012

Hi list,

I use gdal 1.9.0 

I have a NITF image that has 12 bands. The first 8 are I and Q of a quad-pol complex.
I ran "gdal_translate -of NITF -b 9 -b 12 -b 10 -b 11 pp1.NTF test" to get rid of them and keep the last 4 magnitude bands.

However the NITF tags are altered, e.g. the NITF_ISORCE and NITF_IDATIM

Have you seen this? 
I also see "Warning 1: FHDR=NITF02.1 not supported, switching to NITF02.10."  Can this be the cause?

Thanks,
Shawn
