NITFS DATA EXTENSION SEGMENT REGISTER
Updated: 5/17/2016 4:07:40 PM

The NITF Technical Board oversees four types of DESs; these four are identified as such:

  • Controlled - DESs essential to product functionality at the enterprise level (e.g. data discovery, dissemination, exploitation, etc.). Configuration management overseen by NTB.

  • Registered - DESs serving program specific purposes with no significance to the product's functionality at the enterprise level. Configuration management overseen by producer.

  • Reserved - DESs under development, controlled or registered to be determined upon NTB review.

  • Observed - DESs observed in use with no knowledge and/or specification on its functionality.

GENERAL DESCRIPTION / REMARKS
OPEN_SKIES_MULTI_MATES
RESERVED
Name Reserved. Pending publication of configuration managed specification. The OSMPF has developed an OSDEF 1.0-to-NITF 2.1 conversion tool, which sometimes produces an "OPEN_SKIES_MULTI_MATES" DES to record related Open Skies datasets in OSDDEF format with each other and their converted NITF 2.1 filenames.
OPEN_SKIES_IMAGE_METADATA
RESERVED
Name Reserved. Pending publication of configuration managed specification. The OSMPF has developed an OSDEF 1.0-to-NITF 2.1 conversion tool, which sometimes produces an "OPEN_SKIES_IMAGE_METADATA" DES to record metadata which has been stripped out of the Image Data (pixel) portion of an OSDDEF Image Segment. Since OSDDEF and NITF are both BIIF compliant, the metadata structures are similar but not identical. This DES will allow metadata which is actually embedded in the pixel data of an OSDDEF Image Segment to be moved to a NITF DES in the resulting NITF 2.1 file.
OPEN_SKIES_ICD_TEXT_FILE
RESERVED
Name Reserved. Pending publication of configuration managed specification. The OSMPF has developed an OSDEF 1.0-to-NITF 2.1 conversion tool, which sometimes produces an "OPEN_SKIES_ICD_TEXT_FILE" DES to record infromation concerning Member Nation-defined metadata structures present in a source OSDDEF file. This DES will allow Member Nation-defined (akin to User defined_metadata descriptions) to accompany the NITF 2.1 converted Open Skies datasets.
OPEN_SKIES_HEADER_DATA
RESERVED
Name Reserved. Pending publication of configuration managed specification. The OSMPF has developed an OSDEF 1.0-to-NITF 2.1 conversion tool, which sometimes produces an "OPEN_SKIES_HEADER_DATA" DES to record OSDDEF-specific metadata from the source file's Image Segment Subheaders. Since OSDDEF and NITF are both BIIF compliant, the metadata structures are similar but not identical. This DES will allow metadata which does not translate directly from OSDDEF Image Segment Subheaders to NITF Image Segment Subheaders to be recorded in the NITF file.
MOVING TARGET REPORT
RESERVED
The MOVING TARGET REPORT identifier is reserved awaiting development and approval of the specification for placing moving target related data elements within an NITF DES.
ICC_PROFILE_SUPPORT_DES
RESERVED
ITT Corporation is registering this DES to allow NITF 2.1 files to contain ICC Profile data and associated metadata indicating how the profiles should be applied to the image data contained in the NITF file. The ICC_PROFILE_SUPPORT_DES provides a metadata encoding that will support the delivery and application of ICC Profiles to facilitate color-management within softcopy display software used to render NITF files.
FIA-specific DES
RESERVED
Pending IOC National Reconnaissance Office (NRO)/Future Imagery Architecture (FIA). Call the JITC NITFS Test Facility at Commercial (520) 538-5458.
CSSTAT
RESERVED
For hyperspectral products. The NITF2.1 profile for Hyperspectral products requires a compliant NITFS Data Extension Segment Subheader as defined in MIL-STD-2500C. Inclusion of an Statistics DES within the NITF file is optional. The statistics data is read in from a format-specific STA file. The statistics products are then all formatted and stored in the NITF file as a single data vector of double-precision type in the following order: MAX, MIN, MEAN, STDV, EIGENVALUE, EIGENVECTOR, COVARIANCE MATRIX.
CSSLIA
RESERVED
For hyperspectral products. The NITF2.1 profile for Hyperspectral products requires a compliant NITFS Data Extension Segment Subheader as defined in MIL-STD-2500C. The contents of the Spectral Library (SLI) file shall describe the spectral signatures of the DCC Atmospheric Coefficients.
