[gdal-dev] subdatasets not read in a HDF file

[Joaquim Luis]

Hi,

I'm having troubles reading a SeaWifs L2 hdf file due to a bug in the 
hdf driver. The problem here is that not all Subdatasets are read.
Below is the list givem by gdalinfo, which lacks 2 subdatasets: the
cntl_pt_cols & cntl_pt_rows
To prove I attach a little screencapture of "HDF Explorer".

Now I have two questions.

1- The hdf file in question is relatively small (1.2 Mb). Can I attach 
it to a ticket?

2- If I build GDAL with netCDF4, can I force the reading of this file 
with the netCDF driver? And if yes, how?

Thanks

Joaquim
