-----------------------------------
> Geographic/geocentric conversion fails if the geographic CRS is

> Key: SIS-376
> URL: https://issues.apache.org/jira/browse/SIS-376
> Project: Spatial Information Systems
> Issue Type: Bug
> Components: Referencing
> Affects Versions: 0.7, 0.8
> Reporter: Martin Desruisseaux
> Assignee: Martin Desruisseaux
> Priority: Major
> Fix For: 1.0
>
>
> Following Java code:
> {code:java}
> GeographicCRS geographic = CommonCRS.WGS84.geographic();
> GeocentricCRS geocentric = CommonCRS.WGS84.geocentric();
> CRS.findOperation(geographic, geocentric, null);
> {code}
> fails with the following exception.
> {noformat}
> org.apache.sis.referencing.factory.InvalidGeodeticParameterException: Les
> transformations « Affine parametric transformation » et «
> Geographic/geocentric conversions » ne peuvent pas être combinées. Les
> dimensions des objets (2D et 3D) ne concordent pas.

> If we replace the call to {{geographic()}} by a call to {{geographic3D}},
> then the code succeed and the converted coordinates are corrects.
