OperationNotFoundException when sourceCRS is a ProjectedCRS + VerticalCRS
-------------------------------------------------------------------------
Key: GEOT-1783
URL: http://jira.codehaus.org/browse/GEOT-1783
Project: GeoTools
Issue Type: Bug
Components: core referencing
Affects Versions: 2.5-M0
Reporter: Martin Desruisseaux
Assignee: Martin Desruisseaux
{{DefaultCoordinateOperationFactory.createOperation}} works as expected with 3D
or 4D source CRS in the following cases:
* No datum shift.
* Datum shift required but no vertical axis (only a temporal one).
* Datum shift required but the 3D CRS is a {{GeographicCRS}} with height above
the ellipsoid.
But it doesn't work anymore in the following cases:
* Datum shift required and the vertical axis is height above the geoid. This is
the subject of "referencing 3D" and will not be discussed further in this issue.
* Datum shift required, the vertical axis is height above the ellipsoid and the
horizontal CRS is a {{ProjectedCRS}}.
The last failure is unexpected. I suspect (but didn't tested) that it would
occur with any derived CRS, not just {{ProjectedCRS}}. Steps to reproduce:
{code:java}
@Test
public void testProjected4D() throws Exception {
CoordinateReferenceSystem targetCRS = CRS.decode("EPSG:3395");
CoordinateReferenceSystem sourceCRS = CRS.decode("EPSG:27572");
sourceCRS = new DefaultCompoundCRS("3D", sourceCRS,
DefaultVerticalCRS.ELLIPSOIDAL_HEIGHT);
sourceCRS = new DefaultCompoundCRS("4D", sourceCRS,
DefaultTemporalCRS.JULIAN);
CRS.findMathTransform(sourceCRS, targetCRS);
}
{code}
Results:
{code:none}
