Seems like GDAL is no longer needed.

However, it is likely that we will need HDF5 + NetCDF-4 in the future, for storing the output of the sound propagation calculations. (NetCDF-4 is widely used storage format in the geospatial sciences so would make sense to use it.)

HDF5 and NetCDF4 C librarires are installed automatically with Anaconda.

On Linux they can be installed with,

sudo apt-get update
sudo apt-get install -y --reinstall build-essential
sudo apt-get install -y software-properties-common
sudo apt-get install -y libhdf5-serial-dev libnetcdf-dev libnetcdff-dev  # Install HDF5 and NetCDF-4 C libraries

BUT: We have to be mindful that most users will be on Windows and Mac. (This is really important - always think of the users!) Therefore, I favor the Anaconda approach.

Of course, we can also include installation instructions for Linux users that do not wish to use Ananconda.

@matt_s your thoughts?
