In 2022 the section of Parma of the Club Alpino Italiano (CAI) created a new 1:25,000 scale hiking trails map of the Parma Apennines. It is a series of 7 printed maps of 70x100 cm format with front/back cartography. The maps were created using OpenStreetMap (OSM) data, with the hiking theme (and more) entirely developed, updated and monitored by the volunteers of the CAI section directly on the OSM platform. We want to describe the entire process of creating the maps, starting from data processing and cartographic techniques, up to printing in the typography.
