Martin Desruisseaux created SIS-472:
---------------------------------------
Summary: Unexpected lost of vertical coordinate
Key: SIS-472
URL: https://issues.apache.org/jira/browse/SIS-472
Project: Spatial Information Systems
Issue Type: Bug
Components: Referencing
Affects Versions: 1.0
Reporter: Martin Desruisseaux
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}
