Scans-to BIM for the Cultural Heritage: first results of a study case for a medieval church and its urban context

Raw data, first acquired by several and integrated geomatic procedures and subsequently processed so as to achieve a 3D geometrical model, are the basis for conservation and preventive maintenance of the Cultural Heritage; furthermore, they also allow for the employment of the BIM, Building Information Modeling methodology. By using point clouds elaborated by terrestrial laser scans this research has as main objective the implementation of the BIM technology for the digitalization of the built heritage. In particular a digital three-dimensional model of the medieval S. Maria della Libera Church in Aquino, in the Southern Lazio has been obtained; it represents all the fundamental construction features of the building, the decorative elements and its localization inside a territorial context rich of history and of historical-artistic-archaeological relevance.
