FAQ
NTF to FLIF 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 FLIF files?
FLIF (Free Lossless Image Format) is a royalty-free format launched at the end of 2015 as "work in progress" with the aim of offering a better alternative for storing lossless images than the existing PNG, WebP, BPG, JPEG2000 and JPEG XR. FLIF provides similar image quality as the other extensions, but in a file size than can be up to 74% smaller. The new format uses a form of the Adam7 algorithm for compressing images, offering progressive interlacing that allows users to obtain a reasonable encoding of an image even from a partial download.
