Martin Desruisseaux updated SIS-249:
------------------------------------
Description:
(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.
See §1.3.5.1 in IOGP Publication 373-7-2 – Geomatics Guidance Note number 7,
part 2 – April 2015.
