[gdal-dev] netcdf driver

[Denis Nadeau]

Chris,

I corrected the namespace problem on my local machine and it worked for me
with Tropical Rainfall data from NASA/GSFC DISC.  I will check in the code
later today.

Also, the problem your having on
http://apdrc.soest.hawaii.edu/dods/public_data/SODA/soda_pop2.0.4 is due to
the fact that you are using GDS(Grads-DODS) which is meant for Grads.

I will look at the source code and try to find out why the IReadBlock
failed.   It might be very simple to fix.  In fact, I think it would be very
nice if GDAL DODS driver support GDS since GDS is georeferenced and a lot of
people doing research are using it.

Thanks for your input!
Denis
