 ====== FIMEX ====== ====== FIMEX ======
  
-Fimex is a the File Interpolation, Manipulation and EXtraction library for gridded geospatial data, written in C/C++. It converts between different, extensible dataformats (currently netcdf, NcML, grib1/2 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. +Please see the wiki on [[https://github.com/metno/fimex/wiki|github]].
- +
-For simple usage, Fimex comes also with the command line program ''fimex''. +
- +
-Fimex is build around the [[http://www.unidata.ucar.edu/software/netcdf-java/CDM/|Unidata Common Data Model version 1]]. +
