[gdal-dev] python GDAL issue

[Edson, Adam Robert]

I can't make the NITF file available, however the relevant portion of the BANDSB TRE should look like (with the type following in parentheses):

        RAD_QUANTITY      = 'SPECTRAL RADIANCE       '  (BCS-A)
        RAD_QUANTITY_UNIT = 'S'                                      (BCS-A)
        SCALE_FACTOR      = '8.0000000E+01'     ( IEEE-754 32-bit float)
        ADDITIVE_FACTOR   = '0.0000000E+00'  ( IEEE-754 32-bit float)
        ROW_GSD           = '0030.00'                                     (BCS-N)
        ROW_GSD_UNIT      = 'M'                                          (BCS-A)
        COL_GSD           = '0030.00'                                       (BCS-N)
        COL_GSD_UNIT      = 'M'                                            (BCS-A)
        SPT_RESP_ROW      = '-------'                                     (BCS-N)
        SPT_RESP_UNIT_ROW = 'M'                                     (BCS-A)
        SPT_RESP_COL      = '-------'                                       (BCS-N)
        SPT_RESP_UNIT_COL = 'M'                                       (BCS-A)
        DATA_FLD_1        = '                                                '(unsigned integer)
        EXISTENCE_MASK    = '2306867200'                    (unsigned integer)
        RAD_ADJ_SURF      = 'DETECTOR                '              (BCS-A)

Can you make the NITF file available? Can you at least post the relevant part of the BANDSB TRE from the file?

I am trying to parse a TRE in a NITF following the spec found here (https://nsgreg.nga.mil/doc/view?i=4829&month=10&day=10&year=2019<https://nam01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fnsgreg.nga.mil%2Fdoc%2Fview%3Fi%3D4829%26month%3D10%26day%3D10%26year%3D2019&data=02%7C01%7Care131%40psu.edu%7C6e7b7d4bbfff4e39787508d74dc32079%7C7cf48d453ddb4389a9c1c115526eb52e%7C0%7C1%7C637063372780065649&sdata=m7L1GEbwkDX5fdJxaCeya4zP5Dg34luNAYUdqA6tx%2Bo%3D&reserved=0>). Specifically, I am having trouble with the BANDSB TRE with the EXISTENCE_MASK field. It is supposed to be an unsigned int that can be used as bit flags for data following after it. I am currently getting garbage at this location from the gdal.getMetadata('TRE') call. Any help would be appreciated.
