Ciao Matthias!

Sono anche tedesco e il mio Italiano e malo - uso Inglese.

The GTA is one of my pet projects. During the last years, I have made an 
attempt to map as much of the GTA as possible for OSM, but so far I have 
only managed to do so from Susa northwards. Most of this northern part, 
including variations like the 'variante Walser', plus the lesser-known 
continuation in the northern tip of the Piemonte, finally ending in 
Cannobio on the shores of Lago Maggiore, are mapped. The trail is mostly 
tagged as 'GTA' or 'grande traversate delle alpi'. I walked 95% of the 
northern half myself, recording GPS tracks with my etrex and publishing 
what was missing - my personal estimate is that ca. 60% were there 
already. Now, in the north, very little is missing, but parts of the 
route are not tagged GTA or tagged only with their local numbers, and 
some of the trails are missing an SAC classification. The route changes 
from time to time, so some data on OSM may be out of date.

I haven't yet gotten round to mapping or even looking at the data south 
of Susa, but I intend to do so in the years to come.

Whoever can contribute to the GTA mapping on OSM is, of course, welcome 
to do so. I doubt, though, that much coordination will be needed. It's 
easy enough to find a section of GTA which is not mapped yet - south of 
Susa ;) and just go ahead and do it. Of course it may be fun to do 
something coordinated. Sadly as far as I know

http://www.klingenfuss.org/gta.htm

is not contributing to OSM. There is a lot of useful info there, though. 
But since more and more of the trail is now on OSM, there is a good base 
of trail information freely available. For those walking with a GPS unit 
(specifically garmins like the etrex and the 60c) I have created a very 
detailed synoptic GPS map from the CTRN and OSM data, which you may find 
useful for your excursions in the area, please have a look at

How about you? All you need is an account with OSM's wiki. Everyone can 
edit it, it's really quite simple! If you feel this page is a good place 
to have a GTA entry, you can simply add it. It looks to me, though, as 
if this page only has a few trails around Torino; for a prominent 
long-distance trail like the GTA a separate page might be better.

I'll happily help improving the GTA data in OSM. I have enjoyed my 
walking on the GTA a lot, and I think the information about it should be 
freely available to everyone. I think the most important parts are 
integrating changes to the route, improving the accuracy by having more 
GPS tracks to work with, and adding missing SAC classifications - but 
there may be other aspects I'm not aware of.

I could say the same. I was assured, though, that english is an 
acceptable language to post in, so I'll stick with it for now.
