FAQ
NTF to CG4 Conversion
What are NTF files?
NTF is an extension used by two different geographic formats. The first is the National Imagery Transmission Format, a US and NATO standard for satellite and aerial images, in which a file can carry one or several pictures together with graphics, text, and detailed information about the sensor, the time, and the security classification. The second is the National Transfer Format of Great Britain, a British Standard from 1988 that is the usual format for digital map data of Ordnance Survey, the national mapping agency, such as contours, elevation models, road and river networks, and administrative boundaries. The two have nothing in common except the three letters, and the first bytes of the file show which one it is.
What are CG4 files?
CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data. CG4 is compatible with a very limited number of digital graphics programs. Files with this extension contain a bitmap that often uses the CCITT4 compression, which is an old fax machine standard used for black-and-white images.
