Subject [jira] [Updated] (SIS-218) Cassini-Soldner (EPSG:9806)
Date Mon, 27 Apr 2020 21:21:00 GMT

     [ https://issues.apache.org/jira/browse/SIS-218?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Martin Desruisseaux updated SIS-218:
------------------------------------
    Description: 
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.
