Abstract
[EN] In the procedures regarding built heritage documentation, the process of representing the object in a digital \nenvironment is characterized by a high level of complexity. In fact, the need to process heterogeneous information, \nreferring to quantity, quality and format is one of the main emerging issues. Recent technologies of digitization of \nour built environment offer excellent performances on data reliability and time of acquisition. On the other hand, \nthey bring about new challenges regarding how to define methodologies and strategies to effectively elaborate \nsuch information. \nA possible way to optimize the use of these data is by implementing them into informative systems: these \ntools have great potential in the creation of multi-layered representations and offer extensive possibilities for \ninterpretations and analyses. \nThis research, carried out by the laboratories DAdaLab and PLAY of the University of Pavia, focuses on the \nUniversity’s Palazzo Centrale and aims at developing a precise methodological approach: starting from the 3D \nacquisition, the survey data are discretized – through critical processes of semantic analysis and breakdown – and \nlater implemented into informative databases. \nMoreover, the architectural characters, construction phases and the strong bond with the urban setting make the \ncase study particularly valuable; therefore, it represents an excellent opportunity to point out the potentials of \nthis approach to the definition of management tools for the conservation of built heritage.
