FAQ
CDF to PGM Conversion
What are CDF files?
CDF is a file extension used for the Network Common Data Format (NetCDF), a self-describing binary format developed by Unidata at the University Corporation for Atmospheric Research (UCAR) to store array-oriented scientific data. A file of this type contains named dimensions, variables, and attributes, which allows multidimensional datasets such as temperature, wind, elevation, or ocean currents to be stored together with the metadata needed to interpret them. Variables are typically organized along coordinate axes such as latitude, longitude, depth, and time, with time often declared as an unlimited dimension that can grow as new records are appended. The format is machine-independent and is widely used in meteorology, oceanography, and climate science. Although the .nc extension is more common, the .cdf extension is also encountered for NetCDF files.
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.
