Description

CoordinateOperationFinder has some corner cases where if fail to find a coordinate operation, or a more appropriate operation could be found. Those corner cases are identified by TODO labels in the code. Some cases are:

In createOperationStep(GeodeticCRS, GeodeticCRS):

• Geographic 2D ⇌ Geographic 3D with datum change: current code can not build a Molodensky operation (it builds that operation only when the number of dimensions is the same).
• Coordinate operation performing change of coordinate system (for example from CartesianCS to SphericalCS) incorrectly named "Affine".

In createOperationStep(GeodeticCRS, VerticalCRS):

• Information about interpolationCRS is lost.
