FAQ
NC4 to CG4 Conversion
What are NC4 files?
NC4 is a file extension used for NetCDF-4, the fourth generation of the Network Common Data Form, a format for storing scientific data that is maintained by Unidata at the University Corporation for Atmospheric Research. It is widely used for weather, climate, ocean, and satellite data, where measurements are organized as multidimensional arrays, for example temperature at a grid of locations over time. A file describes itself: it holds the data together with names, units, and notes on what they mean. NetCDF-4 appeared in 2008 and uses the HDF5 format underneath, which allows data to be compressed and grouped in folders inside the file. Although the official recommendation is to use the .nc extension for all versions, some data providers choose .nc4 to mark the newer format.
What are CG4 files?
CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data. CG4 is compatible with a very limited number of digital graphics programs. Files with this extension contain a bitmap that often uses the CCITT4 compression, which is an old fax machine standard used for black-and-white images.
