Martin Desruisseaux commented on SIS-284:
-----------------------------------------
Before to close this task, we need to verify that we can decode all the
following coordinate operations:
{code:java}
public class Test {
public static void main(String[] args) throws Exception {
CoordinateOperationAuthorityFactory factory =
(CoordinateOperationAuthorityFactory) CRS.getAuthorityFactory("EPSG");
System.out.println(factory.createCoordinateOperation("15596")); //
3D to 3D
System.out.println(factory.createCoordinateOperation("1336")); //
3D to 2D
System.out.println(factory.createCoordinateOperation("1335")); //
2D to 2D
}
}
{code}
With EPSG geodetic data set 8.9, the first coordinate operation succeed but the
next two fails, because the operation method is declared with a {{null}}
(meaning arbitrary) source number of dimensions, which is okay, but a target
number of dimensions fixed to 3. If the situation is the same in EPSG geodetic
dataset 9.0, we may need to force the target dimension to null.
