Reading addtional metadata from NITF segments

[gaopeng]

Could you add the following metadata items:

The following metadata tags can be found under the PIAIMC segment:

CLOUDCVR
SENSNAME
MEANGSD

The following metadata tags can be found under the CSEXRA segment:

SENSOR
PREDICTED_NIIRS
CIRCL_ERR
LINEAR_ERR

Attactched contains more info on these segments.

Gao,

Are you aware you can already fetch the raw value of these TREs via the "TRE" domain?

eg.

const char *pszValue = GDALGetMetadataItem( poDS,"PIAIMC", "TRE" );

this is described at the bottom of:

​http://www.gdal.org/frmt_nitf_advanced.html

If you still want this broken out as mainline metadata I can do so, but the generic mechanism was put in place to limit the amount of TRE type specific metadata that needs to be handled.

We tried "TRE" domain, and I was told it doesn't return the needed metadata. I'll check again, and get back to you.

Using "TRE" and parsing the string we are able to extract the metadata needed. I am closing this Ticket if there is no other requests for the parsed name-value pairs.
