Re: hdf4/hdf5 [Fwd: Re: HDF4 support]

Hi Rob:

We are looking for funding (or another group) to add an HSF4/HDF-EOS reader to 
the CDM and THREDDS. The NCSA library is in C, but we require 100% Java, so we 
cant use it.

Any ideas from anyone on where we might find resources would be welcome.

I guess we also have a large supply of HDF4 files.   I would 2nd the
motion for HDF4 support in Thredds :)

NCSA seems to be a fully operational hdf4 and hdf5 library for java.
How much effort would it take to adapt this for use in THREDDS?

Hi John,

No, I think only HDF5.

The THREDDS Data Server only serves data that the netCDF-java library can read. As Yuan said, it can't read HDF4 but can read HDF5 (though it isn't a full HDF5 implementation, so there are HDF5 files that it can't read).

However, if you are looking for OPeNDAP access, the OPeNDAP project
(opendap.org) does have an HDF4 server.
