NITF is abbrevation of National Imagery Transmission Format, whihc is a raster format standard defined by NITF Standards Technical Board.

Geospatial analysts in different industries use NITF to store multiple types of data in a single file, including imagery, vectors, annotation, and complex metadata.

The NITF format allows for storage and disseminaiton of imaginery and its associated metadata - or the detailed information about the location, context, context, and structure of the image - in a single file. NITF is essential to the interoperability of systems within and among many government organizations worldwde. Further, to ensure proper usage and implementation across systems and customers accessing the NITF data format, the Joint Interoperability Test Command (JITC) certifies systems implementing the NITF format for compliance with the standard.

The NITF is the standard for formatting digital imagery and imagery-related products and exchanging them among members of the Intelligence Community (IC), the Department of Defence (DOD), and other departments and agencies of the United States Government as governed by Memoranda of Agreement (MOA) with those departments and agencies.

The initial NITFS purpose was to standardize the imagery format and associated data being transmitted from/to secondary imagery dissemination (SIDS). Due to the growing NITFS acceptance, it is now being applied to imagery dissemination systems in general, not SIDS alone.  The purpose of NITFS is to transmit a file composed of an image accompnied by subimages, symbols, labels, text, and other information that relate to the image. One of the main features of NITFS is that it allows several items of each data type to be included in one file, yet any data types may be omitted. The NITF file incorporates the CGM standard for graphic and accommodates user-selectable compression for images. The file is submitted to the Message Transfer Facility (MXF), which allows it to be transferred usiing any of a set of user-selectable protocols and media. The output is a message which, by conforming to the standards and their use, is compliant with NITFS.
