I am searching for a file in any geospatial vector format (Shape, ...) with the Alps classified by Suddivisione Orografica Internazionale Unificata del Sistema Alpino (SOIUSA) with the 36 sections and if possible also the corresponding subsections as described in detail on the italian Wikipedia page.

As mentioned in this article there is also a book by the same author called Atlante orografico delle Alpi. SOIUSA with some detailed illustrations. My italian is not that perfect, that I would understand everything but there might be some digital files somewhere.

There is a nice image visualising the classification by Luca Bergamasco, but it is just a PNG: SOIUSA-sezioni by Luca Bergamasco
