Subject [jira] [Created] (SIS-340) Support coordinate transformations between ParametricCRS and VerticalCRS

---------------------------------------

             Summary: Support coordinate transformations between ParametricCRS and VerticalCRS
                 Key: SIS-340
                 URL: https://issues.apache.org/jira/browse/SIS-340
             Project: Spatial Information Systems
          Issue Type: Improvement
          Components: Referencing
    Affects Versions: 0.7
            Reporter: Martin Desruisseaux


{{ParametricCRS}} are used for elevations measured by a pressure, while {{VerticalCRS}} are
used for elevations measured in metres (or other linear units). There is currently no mechanism
for performing coordinate transformations between those two kind of measurements. We need
to implement a mechanism which allow users to plug-in their transformations. This will require
user-provided data, for example pressure at ground level, that may change at every instant.
We may consider leveraging the "dynamic datum" mechanism under discussion (as of November
2016) for ISO 19111 revision.
