An urban modeling protocol through catalogues and technological modules. From digital survey to the 3D information system for the historic center of Bethlehem.

The three-dimensional modelling, aimed at the representation of urban contexts, is closely linked to the theme of communicating information related to the constructive, typological and technological characteristics of the historic city. In particular, the definition of methodological protocols for the creation of extended 3D models is at the center of the research developed in Bethlehem by DAda-LAB Didactics and Research Laboratory of University of Pavia.
