Hi Rich at al:

Sorry, but writing netcdf4 files with Java-Netcdf is much further off than I
had hoped. The problem is that the format has gotten much more complex in
version 1.8 than originally planned, and they have plans to continue to change
it. At the moment, Im just trying to get the reading done correctly. After
that, we'll have to see what resources it will take to add writing.

Guys,

Just in case you are not on this list.   I downloaded the ToolsUI
viewer and used it to successfully open and view (see attached screen
grab) the unstructured mesh hdf5-based XMDF file at

http://stellwagen.er.usgs.gov/models/mesh_datasets.h5

which is very encouraging!   Since we can read XMDF files with
NetCDF4, I assume this means we could write them also (right John)?

We have a very preliminary version of netcdf-java 4.0 at:

  http://www.unidata.ucar.edu/software/netcdf-java/

At the moment what we need is anyone who uses netcdf4 or hdf5 files
who is willing to use the netcdf-java library to read and compare to
truth (i.e the C libraries and other tools).

You can do this programatically, or just use the ToolsUI Viewer
(version 4.0) at:



http://www.unidata.ucar.edu/software/netcdf-java/v4.0/webstart/netCDFtools.jnlp


(Just open the files in the Viewer tab. To dump data, select the
variable and right click and select "NCdump data". If running from
webstart, its a good idea to have the Java Console running so you can
see any error messages.)

We are looking for problems with any valid netcdf4 / hdf5 file that
exists, including hdf5 1.8+, npoess, hdf5-eos, etc (sorry, no hdf4
files!). Please let us know what problems you see, along with a test
file.

Thanks for any testing help that you can provide!
