[gdal-dev] NSIF with GDAL

[Bar Ori]

Hi Even,
Thanks for your quick response.
I have already read and worked according to this document  (http://gdal.org/frmt_nitf.html)
Still, after removing the aux.xml file, the data is gone with it.
Moreover, this document talks about specific info which is relevant to NITF header, but I have an additional information that is not part of NITF (my metadata is relevant to NSIF - STANAG 4545).

Ori,

Quoting http://gdal.org/frmt_nitf.html:
"""
 Creation Options:

    * Most file header, imagery header metadata and security fields can be set with appropriate creation options (although they are reported as metadata item, but must not be set as metadata). For instance setting "FTITLE=Image of abandoned missle silo south west of Karsk" in the creation option list would result in setting of the FTITLE field in the NITF file header. Use the official field names from the NITF specification document; do not put the "NITF_" prefix that is reported when asking the metadata list.
"""

The full list of creation options is given by:
gdalinfo --format nitf

In C#, that would be something like

string[] options = new string [] {"FTITLE=mytitle"};

Dataset out_ds = drv.CreateCopy("out.ntf", src_ds, 0, options, null, null); or Dataset out_ds = drv.Create("out.ntf", width, height, bands,
                                             DataType.GDT_Byte, options);
