GFF to HPG 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 HPG files?
HPG is a vector image format created in a standard programming language called HPGL (Hewlett-Packard graphics language). Other extensions created in this language include PLT, HP2 and PL2. All are called "plotter files" and are created by drawing programs such as AutoCAD to be printed using a device specialized in vector graphics. An HPG file uses a line series of two-letter codes to render an image and can also include parameters.
