Try using a Gridded3DSet with manifold dimension = 2, by getting
rid of the "1" argument. That is, replace:

            (GriddedSet) new Gridded3DSet(radarDomainType, domainVals,
                             bin_count, tiltcount, 1,
                             radarDomainType.getCoordinateSystem(),

by:

            (GriddedSet) new Gridded3DSet(radarDomainType, domainVals,
                             bin_count, tiltcount,
                             radarDomainType.getCoordinateSystem(),

Good luck,
Bill
