[talk-ch] Swisstopo Alti3d

[Simon Poole]

Hi Yves

The Alti3d layer has been included in 
https://github.com/osmlab/editor-layer-index since we've had permission 
to use it. The main issue is that it doesn't cover all of Switzerland 
with the same resolution (yet, I would have to check what the time scale 
is for complete coverage).

But I've used similar (or better) data from the Cantons, for example 
Zürich, to map all kind of stuff in forests, and yes this is often 
superior to any other way of adding/correcting geometries.
