[gdal-dev] NSIF with GDAL

[Bar Ori]

The metadata I am trying to add is according to " STANAG 4545 /AEDP-4 NATO Secondary Imagery Format (NSIF)" (http://www.nato.int/structur/ac/224/standard/4545/4545_documents/4545_ed1_amd1.pdf)
I read about the TRE at http://gdal.org/frmt_nitf_advanced.html but didn't understood exactly how to work with it in my code.
But again, will it be saved on the file itself or on external file? My goal is to have all in one nsf file.

P.S. for viewing the metadata, I am using the FWTool, do you think maybe there is the problem? Maybe this tool cannot read it from the file even when exists?

Thanks, Ori.

That's a bit surprising. See:

$ gdal_translate -q byte.tif byte.ntf -of NITF -co FTITLE=foo -a_srs EPSG:32611 $ rm byte.ntf.aux.xml $ gdalinfo byte.ntf | grep FTITLE
  NITF_FTITLE=foo

It is a bit difficult to comment as you're not very specific about which exact info you're trying to write.

You've the possibility to write content of TREs (for most of them you'll have to compose it manually) in file or image subheaders with the TRE= and FILE_TRE= creation options.
