Is it the way for every kind of height except ELLIPSOIDAL_HEIGHT. This one
should be treated especially (as required by ISO 19111, this is not something I
invented). You should create a 3-dimensional GeographicCRS instead of
concatenating a 2-dimensional GeographicCRS with a VerticalCRS["ellipsoidal
height"]. I suggest to just replace the last declaration by the following one:
public static final CoordinateReferenceSystem gpxCRS =
new DefaultCompoundCRS("gpxCrs",
DefaultGeographicCRS.WGS84_3D,
gpxTemporalCRS);
