As reference material concerning trails in the Piedmont, I recommend to 
also have a look at

http://www.regione.piemonte.it/retescursionistica/cms/

and there especially their webgis

http://www.regione.piemonte.it/sentgis/jsp/cartografia/mappa.do

afaict the GTA is not mapped there, but a lot of the GTA uses the 
regular trail network and is therefore covered by this data set.

Linking to this page might be helpful, but I haven't yet found a way to 
refer to a specific view in their GIS (like, with coordinates and 
resolution). I'm not sure, but maybe one could get proper WMS access to 
their data and pull them into JOSM for crossreferencing; I think we 
can't just use them in OSM because the license is incompatible. Anyway, 
the presentation of the data is getting better and the webgis is quite 
nice already - they even have photographs along the trail :)

If I remember rightly, the Regione cooperates with the CAI to verify the 
trails in the data set. I don't know how much has been verified already. 
We might help getting the work done, since we are out there with our GPS 
units mapping, but I don't have the contacts to make such proposals.

I have talked with dati.piemonte.it, who also provides access to the 
legacy trail network to find out if the trails could somehow be accessed 
in vector format (to include them in my map), but so far it's tiles only 
for the public, even though originally I am quite sure the data is 
vector. Still a good resource, and they may eventually provide vector 
data if enough people ask nicely ;)
