This ongoing project at the University of Trento aims to create a Historical GIS based on the strategic-level military maps from World War I used by the Italian Army General Staff to conduct operations during the conflict. Physically stored by the Archive of the Historical Office of the Army General Staff, these maps were first bound and then digitised via plotter by the Italian Military Geographic Institute, and subsequently delivered in this format to the Centro Geo-Cartografico di Studio e Documentazione (GeCo) for geo-historical enhancement. The main objective is the digitisation of the overlaid elements, such as brigades, army corps and other military units, present on the topographic bases drafted by the Italian Military Geographic Institute during the war years. Following appropriate georeferencing, data originally overlaid on these digital maps will be extracted and digitised, creating thematic layers representing military units and their positions over time. This will allow the reconstruction of troop movements and the evolution of the military context in the North-East Italian territories during the Great War. The resulting GIS portal will offer the visualization of thematic polygons, lines and points, and will allow queries within its system. Users will be able, for example, to search for the location of a brigade on a specific date, identify military units present in a particular area and analyse strategic changes over time. This tool could be useful for both historical researchers and the public, providing a new way to explore and understand the dynamics of World War I in the Triveneto region of Italy. Additionally, the digitisation of historical cartographic data would contribute to the preservation and enhancement of documentary heritage. Thus, the project aims to bridge the past and the present, creating an interactive digital archive capable of providing new perspectives on the events of the Great War.
