FAQ
NTF to PPM 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 PPM files?
PPM or Portable Pixelmap files are image files included in Netpbm, an open source graphics program. The other widely used Netpbm formats are PGM (Portable Graymap) and PBM (Portable Bitmap). All three are image formats and are sometimes called collectively PNMs (Portable Anymap format). While PGMs contains grayscale images, PPMs include color images and they represent intermediary files used in the conversion of less known formats using the Portable Bitmap Utilities. PPM files are mostly operated on UNIX and Intel-based platforms.
