---------------------------------------
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".
