Hello,

for those of you who may have experience with GDAL, how comprehensive is the
support of the GDAL libraries for NetCDF?  Is this support equivalent to the
NetCDDF libraries provided by UNIDATA and what version of the UNIDATA NetCDF
libraries in particular.  ie: with GDAL's netcdf implementation will one be
able to bring the range of sample netcdf data files listed on
http://www.unidata.ucar.edu/software/netcdf/examples/files.html.

Vardis,

Hopefully others can speak to this in more detail, but I wanted to stress
that the GDAL netcdf driver uses UNIDATA's netcdf library.  It will not
support all netcdf files.  In particular it tries to map the netcdf arrays
to appears as images (2D grids) in GDAL and if it fails to establish a
mapping it will give up.  Lots of auxilary information is not exposed
through GDAL and many array configurations are likely inaccessable through
GDAL.

Best regards,
