Re: [thredds] Compression by Gathering working with Thredds?

Hi Matthias,

No, the underlying netCDF-Java library does not handle CF "compression
by gathering". From this fairly recent (June 2011)  discussion on the CF
mailing list

http://mailman.cgd.ucar.edu/pipermail/cf-metadata/2011/022125.html

it doesn't sound like it is used very widely. As suggested there, you
might consider netCDF-4 chunking/compression instead. Which is handled
by the netCDF-Java library and so by the TDS and ncWMS.
