Scientific Data Formats
IDL supports the HDF (Hierarchical Data Format), HDF-EOS (Hierarchical Data Format-Earth Observing System), CDF (Common Data Format), and NetCDF (Network Common Data Format) self-describing, scientific data formats. Collections of built-in routines provide an interface between IDL and these formats. For specific routine and object information used in IDL to access these type of files, see the Scientific Data Formats category under "Input/Output" (IDL Quick Reference).
