Hello Marilena, this is a subjects by itself, mixing open data, crowdsourcing, big data, research data, etc. It's not only a sort of webography, but also asks for an accurate evaluation of viability for a given project. Anyway, here is the Free GIS Datasets (Categorised List): http://freegisdata.rtwilson.com/ Expecially noteworthy for Italy, as you surely already know, is the Portale cartografico nazionale (http://www.pcn.minambiente.it) and the data of the geoportals of italian regions (see here: http://www.centrointerregionale-gis.it/, a table a little after half-page - it's a long page). Still about Italy and open data, GFOSS used to collect references here http://gfoss.it/drupal/geodati, and the dedicated http://www.opengeodata.it/ site (related initiatives, few specific references) among others show the results of italian efforts towards open data. Beware, as sometimes happen, open data means not-live-anymore-data or at least not-necessary-up-to-the-declared-date (formally accurate metadata usually hide vague and fussy reference to the date of survey). Don't underestimate OSM expecially for local development projects. It's becoming much better than official cartography because of the difference between remote sensing (and photogrammetry) and direct survey.
This for my two (Euro)cents...
