> Conversion from projected (x,y,h) to geographic (φ,λ,H) coordinates causes the lost of vertical coordinates, which is set to NaN. Actually given that operation implies a transformation from geoidal to ellipsoidal height and SIS-362 is not yet fixed, we would rather expect an exception to be thrown. Code to reproduce:
> {code:java}
> import org.apache.sis.referencing.CRS;
> import org.apache.sis.referencing.CommonCRS;
> import org.opengis.referencing.crs.CoordinateReferenceSystem;
> import org.opengis.referencing.operation.CoordinateOperation;
> final class Test {
>     public static void main(String[] args) throws Exception {
>         CoordinateReferenceSystem sourceCRS = CRS.compound(CRS.forCode("EPSG:2154"), CommonCRS.Vertical.MEAN_SEA_LEVEL.crs());
>         CoordinateReferenceSystem targetCRS = CommonCRS.WGS84.geographic3D();
>         CoordinateOperation op = CRS.findOperation(sourceCRS, targetCRS, null);
>         System.out.println(op);
>         System.out.println();
>         System.out.println(op.getMathTransform());
>     }
> }
> {code}
