Re: getDataIterator methods in PointObsDataset

You know you can currently use:

 public List getData( ucar.unidata.geoloc.LatLonRect boundingBox, Date start, 
Date end, ucar.nc2.util.CancelTask cancel) throws IOException;

The getDataIterator() will allow certain efficiencies in dealing with very 
large datasets. I would advise to get the Iterator on the List you get from 
getData(), and use that, so that it will be easy to switch to getDataIterator() 
when that is ready. Wont be for some months.
