FAQ
PRF to PGM Conversion
What are PRF files?
PRF is an image format of PHOTOMOD, a photogrammetric software system of the Russian company Racurs that is used to process aerial and satellite photographs and to produce maps and elevation models. The format is also known as MegaTIFF. It was created for very large images, which can exceed 4 GB and cannot be saved in an ordinary image file. The picture is cut into smaller parts that are stored in separate files, and a small overview picture is added so that the whole image can be shown quickly at a small scale. A short .prf file ties all of the parts together and describes the image. A related variant for elevation data uses the .x-dem extension.
What are PGM files?
The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
