FAQ
SG-GRD-Z to PGM Conversion
What are SG-GRD-Z files?
SG-GRD-Z is a compressed grid file of SAGA GIS, a free, open-source geographic information system used for terrain analysis, hydrology, soil science, and climate studies. A grid is a map made of equal cells with one value in each, such as an elevation model. The older SAGA format keeps such a grid in several separate files: one with the values, one with the description, and often one with the projection. A file with this extension packs all of them into a single archive, which is more convenient to store, copy, and send, and which takes less space because the data are compressed. The archive can be opened in SAGA GIS like an ordinary grid, without unpacking it by hand.
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.
