NetCDF (network Common Data Form) is a set of interfaces for array-oriented data access and a freely-distributed collection of data access libraries for C, Fortran, C++, Java, and other languages. The netCDF libraries support a machine-independent format for representing scientific data. Together, the interfaces, libraries, and format support the creation, access, and sharing of scientific data. Optional HDF4 support --------------------- If you need support for reading HDF4 files, please build and install the 'hdf' package from SlackBuilds.org, and then pass the option 'HDF4=yes' to the netcdf SlackBuild, for example HDF4=yes ./netcdf.SlackBuild
