Swiss Grid Systems
May I suggest that interested participants in this discussion thread open:
and on the documentation entry on the right click on Reference system
CH as well as on the Transformation CH1903<->WGS84 for the official
version dated 19.11.2008?
They are available in English, German and French.
For those requiring higher accuracy for non-GIS geodetic
purposes, browse through the superb pages of the Swisstopo site for
the finest documentation I have seen anywhere.
The NTv2 grid data is available in the topic Transformation data and
formulae CHENyx06 of March 2007. See for example
for much more.
