MIL-HDBK-1300A
4.1.3 Implementation. Currently, by Office of the Assistant Secretary of Defense for Command, Control, Communications, and Intelligence (OASDC3I) directive, NITFS is mandated for all DOD SIDS. In May 1989, the Chairman of the Committee on Imagery Requirements and Exploitation (COMIREX) directed the adoption of the NITF as the Intelligence Community standard for the transmission of secondary images.
4.2 Description of NITFS. The purpose of the NITFS is to transmit a file composed of an image accompanied by subimages, symbols, labels, text, and other information that relate to the image. One of the main features of the NITFS is that it allows several items of each data type to be included in one file, yet any data types may be omitted. Figure 3 illustrates the functional relationship of the components of the NITFS. The figure illustrates imagery, graphics, and text (documents and labels) as input to the formation of a NITF file, which incorporates the CGM standard for graphics and accommodates user-selectable compression for images. Then the file is submitted to the Message Transfer Facility (MXF), which allows it to be transferred using any of a set of user-selectable protocols and media. The output is a message which, by conforming to the standards and their use as illustrated, is compliant with the NITFS.
