Hi Gökhan,

Try to use "pyhdf"

wget -c http://ufpr.dl.sourceforge.net/project/pysclint/pyhdf/0.8.3/pyhdf
-0.8.3.tar.gz
tar zxvf pyhdf-0.8.3.tar.gz
cd pyhdf-0.8.3/
sudo apt-get  install libhdf4-dev
sudo apt-get  install python2.6-dev
cd pyhdf
sudo apt-get install swig
swig -python hdfext.i
cd ..
export INCLUDE_DIRS=/usr/include/hdf
export LIBRARY_DIRS=/usr/lib
export NOSZIP=1
python setup.py install


May be you could use h4toh5 and use pytables.

2 - I'm trying to get ocean color variables through pyhdf package, but I'm
still working on.
If you have any advance, post here your feedback, please.

Regards,
Arnaldo

> and IDL. Except the reflectance correction via NDVI, ms2gt and IDL parts
> seem to be implemented in Python.

> Till now, I have some progress combining GOES imagery with aircraft data.
> My next task is to combine MODIS data with aircraft and radar data. I would
> be happy to get some guidance and code support if there is any previous
> work been done using Python.

> Thanks.
