Nelson,

actually i trying to understand it myself. i'm looking at
netcdf java code at src/ucar/ma2 dir

      Array data = Array.factory(datatype.getPrimitiveClassType(),
Range.getShape( section));
      IndexIterator ii = data.getIndexIterator();
      Range range = (Range) section.get(0);

      for (int r=range.first(); r<=range.last(); r+= range.stride())
             ii.setLongNext( values[r] );

the range is the shape,  the values arrays is the initial dataset, and the
data Array is the resulting polygon.

datatype.getPrimitiveClassType() resolves to LONG in this case.  it might
be easier if you wrote your own code to do the above steps.
