NITF to CAL Conversion
What are NITF files?
NITF (National Imagery Transmission Format) is a file format developed in the United States for exchanging satellite and aerial imagery in a standard way, and it is also used by NATO under the name NSIF. A file of this type works as a package: it can hold one or several images together with vector graphics, labels, symbols, text, and a large amount of descriptive information about the source of the data, such as the sensor, the time, the accuracy, and the security classification. The format was created for secondary imagery from overhead collection platforms, and it became the common language of military and intelligence imagery, and of commercial satellite data. The current version is described in the Joint BIIF Profile. Files may use the .ntf or .nitf extension.
What are CAL files?
A CAL image file represents a monochrome bitmap image that uses the CALS raster image standard for storing graphics data. This standard was created in the 1980s by the US Department of Defence as a compressed interchangeable image format. CAL and CALS are extensions used for similar purposes.
