2019-02-11Make tmerc an alias for etmerc. (#1234)Kristian Evers
* Make tmerc an alias for etmerc This switches the algorithm used in tmerc to the Poder/Engsager tmerc algorithm. The original tmerc algorithm of Evenden/Snyder origin can still be accessed by adding the +approx flag when initializing a tmerc projection. The +approx flag can also be used when initializing UTM projections, in which case the Evenden/Snyder algorithm is used as well. If a tmerc projection is instantiated on a spherical earth the Evenden/Snyder algorithm is used as well since the Poder/Engsager algorithm is only defined on the ellipsoid. +proj=etmerc can still be instantiated for backwards compatibility reasons.

2019-01-08ISO19111: remove PROJ.5 specific format for CRS (refs #1214)Even Rouault
As discussed in https://github.com/OSGeo/proj.4/issues/1214#issuecomment-452084720, the introduction of a new PROJ.5 format to export CRS using pipeline/unitconvert/axisswap as an attempt of improving the PROJ.4 format used by GDAL and other products is likely a dead-end since it is still lossy in many aspects and can cause confusion with coodinate operations. Consequently the PROJ_5 convention will be identical to PROJ_4 for CRS export. Note: on the import side, I've kept the code that could parse unitconvert and axisswap when building a CRS definition from a pipeline. It is there as a hidden feature as it was kind of a tear to remove that code in case it might still be useful...
