Since all the information is in the Gridded3DSet, you don't need
a FlatField. Construct a DataReferenceImpl, pass your Gridded3DSet
to its setData() method, and pass the DataReferenceImpl to the
addReference() method of your display. You'd only need a Field if
you had other information dependent on lat, lon and alt, such as
temperature.
Good luck,
Bill
