Creating NITF images requires a NITF license. This chapter offers information about how to create National Imagery Transmission Format (NITF) images with GeoExpress.
The acronym NITFS sometimes seen refers to the NITF standard, which was created by the Department of Defense as a means of formatting digital imagery and imagery-related products and exchanging them among members of the intelligence community, the Department of Defense (DOD), and other government departments and agencies. NITF was created partly because government agencies needed a single common image representation that supported certain metadata features and workflows. While it is called an image format, NITF is perhaps more precisely described as a file format that wraps image files and metadata about those files.
The NITF format requires information is entered on numerous metadata fields on several forms. For NITF JPEG 2000 encoding, you can edit the metadata fields – as well as the LizardTech metadata tags – in the Metadata Manager.
For details about how GeoExpress saves NITF metadata, see NITF Metadata.
NOTE: When you use a NITF file as an input image, sometimes the band order of the image does not match the band order in the metadata. If this is the case, GeoExpress changes the order of bands in output images to match the metadata band order.
