NITF / NSIF

National Imagery Transmission Format. Digital imagery standard for the US intelligence community. Widely used by the U.S. military commands, other U.S. Government departments and agencies, as well as international organizations such as NATO.

Being adopted by civilian organisations as a standard for commercial imagery. Provides a common basis for the storage and interchange of images and facilitates the use of multiple imagery sources and annotations. NITF files can contain multiple images as well as other information such as graphics and text.

The NATO Secondary Imagery Format (NSIF) is the standard for formatting digital imagery files and imagery related products and exchanging them among NATO members. The NSIF is a collection of related standards and specifications developed to provide a foundation for interoperability in the dissemination of imagery and imagery-related products among different computer systems.

Specification Reference: MIL-STD-2500B; STANAG 4545.

The NITF Data Layer preserves the order of Vector and Raster data. With MapLink Pro Studio you need to process the vector and raster in two passes.

Limitations:

The NITF filter is expected to be able to read files of Complexity Level 3. The filter will attempt to read files which are more complex however memory limitations may limit the size of file that can be loaded and processed.

The filter is aimed at reading and display visual data and map data (ICAT values VIS and MAP).

The compression formats supported are: JPEG 2000, JPEG, VQ and None.

The Vector information that is read is expected to be encoded as CGM.

The Image (IREP value) may be MONO, RGB, YcbCr601, RGB/LUT or MULTI. The MULTI channels are decoded as RGB (first 3 channels).
