Martin Desruisseaux updated SIS-370:
------------------------------------
Affects Version/s: 1.5
> Improve CoordinateOperation WKT for axis changes and Molodensky parameters
> --------------------------------------------------------------------------
>
> Key: SIS-370
> URL: https://issues.apache.org/jira/browse/SIS-370
> Project: Spatial Information Systems
> Issue Type: Improvement
> Components: Referencing
> Affects Versions: 0.7, 0.8, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5
> Reporter: Martin Desruisseaux
> Assignee: Martin Desruisseaux
> Priority: Minor
> Fix For: 1.6
>
>
> The Well Known Text (WKT) formatting of {{CoordinateOperation}} objects have
> the following shortcomings:
> In the formatting of Molodensky Parameters, _Semi-major axis length
> difference_ and _Flattening difference_ parameters are wrongly set to NaN.
> Note that this issue happen only for {{CoordinateOperation}} WKT, not for
> {{MathTransform}} WKT.
> Operation steps inserted for changing axis order are shown as affine
> transform, which is difficult to read for most users. The formatter should
> detect automatically when a matrix is square, of size 3×3 or 4×4 and having 1
> value on anti-diagonal (except last row) and show instead one of the
> following operations:
> * EPSG::15498 — axis order change (2D)
> * EPSG::15499 — axis order change (geographic3D horizontal)
