Hello,
sorry, but I do not speak italian, so I just try it in english.
At the site from "sito di AliLunghe" there you can download a GoogleEarth file, .... the global-slope-locations. You can downlad an update from
Modellflug in Saarmund .
Now there is a new project online, SLOPLE, a real great tool for every sloper (
slople.com )
best regards, and happy sloping,
Harald
