[jira] [Created] (SIS-218) Cassini-Soldner (EPSG:9806)

Martin Desruisseaux created SIS-218:
---------------------------------------

             Summary: Cassini-Soldner (EPSG:9806)
                 Key: SIS-218
                 URL: https://issues.apache.org/jira/browse/SIS-218
             Project: Spatial Information Systems
          Issue Type: Sub-task
          Components: Referencing
            Reporter: Martin Desruisseaux
            Priority: Minor


The Cassini-Soldner projection looks like the Transverse Mercator projection and was more extensively used in past centuries. It would still be useful to port it for historical data. The code in Geotk was originally started by an external contributor. We need to rewrite the formulas for the coordinate projection and inverse projection, using the EPSG guide.

Note that the formulas for the projection derivative can be ported as-is.
