The purpose of this research is the creation of a three-dimensional model of the city center of Ravenna. The creation of a three-dimensional model offers several advantages: first of all, it allows to deepen the knowledge and to represent the city center in its spatial and historical complexity; moreover a three dimentional model represents a tool for interactively explore the virtually reconstructed space, to visualize the archeological sites; to emphasize the most relevant buildings; to simulate interventions on buildings of the urban landscape. To build this model we have defined a method based on the following aspects: - the city center has been divided in multiple areas and each area has been surveyed - a two dimensional survey has been built by using photographic surveys - several graphic bidimensional drawings surveys have been done - to merge surveys, a graphical coding standards of 2dimensional drawings has been applied; moreover a coding standard showed its usefullness in fixing different level of detail. - the orthographic plan joined with the 2dimensional drawings of the fronts allows to shape a three dimensional object - Different criteria have been established to merge several files into an organized master file - The final model of the city center has been exported in *.pdf format.

The generation of a three dimensional model led to an important drawback: the organization of hundreds of working documents in a well structured whole. These documents are: - the carthorgraphic plan used as a container for all the three dimensional models - the carthographic plan used to emphasize the urban structures (i.e. roads, railways, channels...) and the relevant urban nodes (i.e. squares, parkings, parks, harbours...) - drawings of fronts - abacus of relevant architectural elements realized through drawings and orthographic photos - analitical description of materials

Abstract
The purpose of this research is the creation of a three-dimensional model of the city center of Ravenna. The creation of a three-dimensional model offers several advantages: first of all, it allows to deepen the knowledge and to represent the city center in its spatial and historical complexity; moreover a three dimentional model represents a tool for interactively explore the virtually reconstructed space, to visualize the archeological sites; to emphasize the most relevant buildings; to simulate interventions on buildings of the urban landscape. To build this model we have defined a method based on the following aspects: - the city center has been divided in multiple areas and each area has been surveyed - a two dimensional survey has been built by using photographic surveys - several graphic bidimensional drawings surveys have been done - to merge surveys, a graphical coding standards of 2dimensional drawings has been applied; moreover a coding standard showed its usefullness in fixing different level of detail. - the orthographic plan joined with the 2dimensional drawings of the fronts allows to shape a three dimensional object - Different criteria have been established to merge several files into an organized master file - The final model of the city center has been exported in *.pdf format. The last version of this format (8.0), allows the user to visualize and browse the model in several modalities. The generation of a three dimensional model led to an important drawback: the organization of hundreds of working documents in a well structured whole. These documents are: - the carthorgraphic plan used as a container for all the three dimensional models - the carthographic plan used to emphasize the urban structures (i.e. roads, railways, channels...) and the relevant urban nodes (i.e. squares, parkings, parks, harbours...) - drawings of fronts - abacus of relevant architectural elements realized through drawings and orthographic photos - analitical description of materialsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
