[PROJ] How to set target crs in PROJ-data

[Lesparre, Jochem]

Hi,

Traditionally, EPSG has been linking 3D CRSs to 1D physical heights, however this transformation method (e.g. transformation code 9665) is strictly speaking not reversable, since the horizontal coordinates are lost. A year ago, I discussed with EPSG the idea of linking 3D CRSs to a compound CRS of their corresponding 2D CRS + the 1D physical height instead, which would be better as it is reversable. This would require a new EPSG method, so it wasn’t easy to introduce. I am wondering if EPSG did introduce that method now (transformation code 1088?).

Regards, Jochem
