GFF to PPM Conversion
What are GFF files?
GFF (GSAT File Format) is a raster image format developed by Sandia National Laboratories in the United States to store images and image products from its synthetic aperture radar (SAR) systems. The name comes from the Ground-based SAR Applications Testbed (GSAT), the program in which the format was created. A file of this type consists of a header of variable length, which records the configuration and performance parameters of the instrument and the image, followed by a matrix of pixel data. The format was designed to allow custom annotation of radar images, and it has gone through several revisions as Sandia's radar programs developed. It remains the main image format of the laboratory, which keeps a large library of SAR images in this form.
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.
