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.
