Subject [jira] [Created] (SIS-249) Transverse Mercator (EPSG:9807)

Martin Desruisseaux created SIS-249:
---------------------------------------

             Summary: Transverse Mercator (EPSG:9807)
                 Key: SIS-249
                 URL: https://issues.apache.org/jira/browse/SIS-249
             Project: Spatial Information Systems
          Issue Type: Sub-task
            Reporter: Martin Desruisseaux
            Assignee: Martin Desruisseaux


(Note: in the EPSG dataset, Gauss-Kruger and Gauss-Boaga projections are considered to be
the same than Transverse Mercator.)

We could port most of the Transverse Mercator projection in Geotk (after IP review), but the
formulas changed. The formulas used by Geotk were derived from USGS, while the formulas used
by EPSG (called "JHS") are accurate over a wider range of longitudes.

Consequently, we should rewrite the Transverse Mercator projection from the new EPSG formulas.
