Smart survey methodologies for the digitization of architectural drawings. The maps of some convents located in the city of Parma, drawn by Giuseppe Cocconcelli in 1811

This paper regards the field of digitization of archival documentation, with particular attention to the historical iconographic apparatus related to the specific sector of architecture. The operation of dematerialization, essential for the preservation, protection, management, dissemination, and valorization of this heritage, plays a key role in the complex knowledge process of an architectural organism. By illustrating the experimentation carried out on an unpublished collection of survey drawings, drawn by Giuseppe Cocconcelli in 1811, related to some religious structures located in Parma, a reflection on the potential of survey methodologies for the digital documentation of graphic elaborates will be presented. The method adopted represents a possible solution for the digitization of documents that require a digital reproduction that is geometrically correct.
