FOREWORD
The National Imagery Transmission Format Standard (NITFS) is the standard
for the formatting and exchange of digital imagery and imagery-related products
between members of the Intelligence Community. The Intelligence Community is
made up of the Department of Defense (DOD) and other departments or agencies of
the United States Government as defined by Executive Order 12333.
Members of the NITFS Technical Board (NTB) compiled these practices as
an aid to those involved with the implementation and use of the NITFS. The content
is based upon common practices, procedures, and guidelines used in fielded
systems that have successfully implemented the NITFS. To meet a wide range and
variety of imagery-related functional requirements, the NITFS has many
combinations of implementation options to select from. Those implementing the
NITFS should select and apply common practices to meet operational requirements
whenever practicable.
The DOD and members of the Intelligence and Geospatial Community are
committed to interoperability of systems used for formatting, transmitting, receiving,
exchanging, and processing imagery and imagery-related information. These
practices describe the application of the NITFS suite of standards in support of
interoperability among systems within the National Systems for Geospatial
Intelligence (NSGI), systems that interface with the NSGI, and commercial systems
that implement the NITFS.
The suite of standards that comprise the NITFS has evolved over time to
meet the requirements of user systems. These practices address implementation
topics for the NITFS associated with NITF version 1.1, NITF version 2.0, and NITF
version 2.1. Many of these practices are also suitable for use with Standardization
Agreement (STANAG) 4545, North Atlantic Treaty Organisation (NATO) Secondary
Imagery Format (NSIF). Both NITF version 2.1 and NSIF version 1.0 are now
documented in the NSIF01.00 Profile of ISO/IEC 12087-5, Basic Image Interchange
Format (BIIF).
Beneficial comments (recommendations, additions, and/or deletions) and
other pertinent data which may be of use in improving this document should be
addressed to Joint Interoperability Test Command, ATTN: NITFS Test Facility,
2001 Brainard Road, Fort Huachuca, AZ 85613-7051.
