- Downloag and install FWTools, use FWTools 2.3.0 (Windows 32bit) link.
- Install HDF Explorer
- Register HDF Explorer as a viewer for *.nc files (in Windows Explorer Open with ..., then Browse to HDF Explore and check *Always use this program to open ...).
- Convert any source raster file into NetCDF using GDAL:
gdal_translate.exe -of netCDF input_file.asc output_file.nc
- Click on output_file.nc to view it using HDF Explorer.

The architecture taskforce held a meeting (2008-4-15) on the progress of NetCDF as the default output format for Delft3D and SOBEK. The presentation is attached.
Issues discussed (aside from topics mentioned in the presentation):
- Importance of adaptation en extension of the CF standard for output.
- Implementation challenges
- phasing out old tools and libraries (What is the end of life cycle for old file formats?)
- backward compatibility (Will we make sure all old files can be read and written?)
- programming language for conversion tools (Shall we use matlab or another dynamic language to implement the converters?)
- Planning
Agreed was that:
In the next few months we will work on creating converters to import and export cf/netcdf files from and to our current output files. (april - july)
In the 2nd half of this year we will work to change our output formats from his/nefis to netcdf.

Unstruc example requires access to delft3d/sobek repository
NetCDF sources with VS2005 solution requires access to delft3d/sobek repository
To get the netcdf files working under windows you need the following:
Visual studio >= 7, Visual C++ 6 doesnt support long longs, this will work but you have to manually disable large file support.
An updated cfortran.h, A patch has been sent in 2002 to mr burrow, maintainer of the cfortran bridge http://www.unidata.ucar.edu/support/help/MailArchives/netcdf/msg01463.html . I think his whereabouts are not known. The patch is part of default linux distributions.
