Abstract:
Methodology/Approach
The documentation work was conducted on a small fortified town of Tuscany: Poppi. The settlement has Etruscan origins and developed during the Middle Ages, to become the main settlement of the Casentino Valley. The village is surrounded by walls and is characterized by a system of porticoes along the main roads. The documentation project carried out through the realization of a laser scanner survey on a portion of the historic town together with the preparation and the compilation of a database system of the analyzed building units.
Results
The research allowed to develop a methodology to document the historic buildings quickly but with great scientific and metric precision. The information are clearly organized in a database and they can be represented in thematic maps that allow to have a complete overview of the features on the buildings analyzed. The processing of the scans obtained from the laser scanner produced a reliable and accurate survey way to understand the morphology of the buildings and trough a further elaboration on scans it was possible to identify the deformations present on the walls and the parts exposed to structural risk.
Innovations
The methods used allow to document in a complete and detailed way the historical buildings, with great precision and accuracy. In addition to the drawings produced by the survey, the database system organize the data through an analytically reading of the architectural features of the buildings. Finally, the identification of the deformations on the facades is an analysis of the possible structural risk present on buildings, suggesting in which parts may be important to make further investigations.
