Questions & Answers
NITF images: Frequently Asked Questions
What are NITF files?
NITF (National Imagery Transmission Format) is a container made of segments, in which the imagery and everything around it travel together. A file starts with a file header whose first characters, such as NITF02.10, show the version, and which records the security classification, the originator, and the sizes of all the following segments. Then come the segments themselves: image segments, graphic segments for vector overlays, symbol and text segments, and data extension segments for other content. Each image segment has its own header that lists the size, the number of bands, the bit depth, the type of compression, and the way the image is divided into blocks. Compression may be absent, or it may use JPEG, JPEG 2000, or other methods, and images can have several bands. Tagged record extensions, called TREs, add further data such as the geographic position of the image, and a reader that does not know a TRE simply skips it by its length. To convert a NITF file to graphics, a program reads the headers, picks an image segment, decodes its blocks, and arranges them into one picture. Several bands can be mapped to RGB, 16-bit data are stretched to 8 bits for PNG or JPEG, and TIFF or GeoTIFF can preserve the full range and, in the latter case, the coordinates. Because NITF files can carry security markings, the classification fields should be respected when files are shared.
