8. NITF NSIF Format Chapter 1 Introduction The NITF NSIF Format A valid NITF dataset provides a main header identifying the file as a NITF dataset and describing the contents of the file The header is usually followed by one or more data segments Each data segment consists of a segment subheader identifying the type and properties of the data followed by the data itself See NITF Segments on page 8 for more information on data segments Main Header A NITF dataset may contain any or all types of segments available for that version but every NITF dataset must contain a main header The main header describes the entire file including origination information security information file version and size and the number and type of all data segments contained in the NITF dataset Data Segments Data segments can be any of the following types e Security Segments on page 10 e Image Segments on page 11 e Graphic Symbol Segments on page 12 e Label Segments on page 13 e Annotation Segments on page 13 e Text Segments on page 14 e Data Extension Segments on page 15 References For more detailed information about the NITF NSIF format and its components see the technical specifications on the Reference Library for NITFS Users web site NITF Segments While NITF datasets without graphical data are supported most datasets contain one or more displayable segments Displayable segments are image graphic symbol or label segment
