             Summary: Remove usages of Projection sub-interfaces
                 Key: SIS-597
                 URL: https://issues.apache.org/jira/browse/SIS-597
             Project: Spatial Information Systems
          Issue Type: Improvement
          Components: Referencing
    Affects Versions: 1.4
            Reporter: Martin Desruisseaux
            Assignee: Martin Desruisseaux
             Fix For: 1.5


Drop the implementations of {{PlanarProjection}}, {{CylindricalProjection}} and {{ConicProjection}} sub-interfaces. Those interfaces were never part of any OGC or ISO standards. They were added 20 years ago in GeoAPI at the request of users who wanted a classification of map projections. But many classifications exist (based on "conformal" or "equal area" characteristics), and the use of a classification based on "conic", "cylindrical", _etc._ is arbitrary. We are not aware of code for which those GeoAPI interfaces are important.

This cleaning is part of SIS-592: upgrade to ISO 19111:2019. We try to be closer to the standard. Note that the removal of those interfaces do not impact the Apache SIS capability to perform map projections. They are just not classified anymore as "planar", "conic" or "cylindrical".
