Visualising Drawings: from Archives to QGIS. A methodological overview

This paper aspires to propose a methodology to visualize and preserve the documentary heritage in museum archives, using the case study of the Archaeological Park and Museum of Lilybaeum-Marsala (TP, Italy). In particular, we will focus on those documents that have the possibility of being georeferenced, such as maps, project plans and excavation surveys contained in the archives of the Park and the Superintendence for Cultural and Environmental Heritage of Trapani. It is therefore a matter of re-proposing an objective history, considering the printed papers as the bearers of objectivity and immodifiability, the "written" history of the folders. In particular, here we will look at the methodology applied to the visualization of the boards drawn by the architects for the perimeter of the park. Approximately 50 boards including design drawings, satellite photos and the excavation surveys carried out since the first project to establish the park were analyzed. All the material was georeferenced in QGIS for more precise and agile consultation. The use of this method will give not only the possibility to understand and visualize the chronology of the works, of the choices made for conservation, but also to prospect future works for layouts and to better plan exploratory essays and archaeological excavations.
