Fimex is a the File Interpolation, Manipulation, and EXtraction library for gridded geospatial data. It converts between different, extensible data formats (currently netcdf, NcML, grib1/2, metgm, wdb, and felt). It enables you to change the projection and interpolation of scalar and vector grids. It makes it possible to subset the gridded data and to extract only parts of the files. For simple usage, Fimex also comes with the command line program fimex.
METAMOD is a portal solution providing Discovery, Access and Retrieve functionality for scientific datasets along with tools for DAR metadata like automatic extraction, manual editing, and conversion between different formats. Metadata can be converted to different formats and exposed using different search interfaces, i.e. ISO23950 and OAI-PM. It has been designed to be easily integratable with OpENDAP or FTP data servers, and allows data to be uploaded through FTP and HTTP interfaces. A WMS client is built in for visualizing the data.
