Abstract. The technological solutions, made available today, offer opportunities of great interest for the detection in the field of cultural heritage; instrumentation for the survey and advanced multimedia representations for objects of archaeological, artistic, architectural.

Since we changed the type of information, not more interpretation consists of a single piece of data, but from a set of data, must be changed, consequently, also the systems for their management or better, if until now the only situation of interest was that of having to deal with the data representing only the text, data are now made up of sounds, images, video and three-dimensional models. For these reasons and others, we can discuss in continuation, systems and storage structures classics are still not sufficient to manage these new realities.

An architectural structure is a set of three-dimensional components that define spatially a form and a project idea; so that the representation of the architecture may not avail itself simply means two-dimensional graphs to describe it and describe it in all its parts, but need, and it is now possible, systems that provide for the possibility to analyze from multiple points of view the forms that compose it.

The communication media can play a very important role to get directions on the actions of restoration and enhancement of the cultural and environmental heritage. Help can be provided by information and its simulation systems of virtual reality with which, in addition to conveying information, you can view models to better describe the development that the well has had in history. This research starts from the need to develop new systems of representation and data management. Objective of the project is to increase and share knowledge of architecture and the environment. Dynamic representations, relational databases, devices use data, are the main tools of this research.

The study addressed led to the creation of a system that allows the transmission and analysis of data collected and, at the same time, also creates the possibility of access to users not experts in the field of 3D graphics; this has been made possible through the development the project "3DWS" (3D | WEB | SURVEY).

The project involved the creation of a container structured as a web site, in which were placed the materials collected and processed including sketches, photographs, vector data, three-dimensional models and analysis issues. Within this system, three-dimensional models developed were then used as a communication tool with immediate visual link to sub-pages with a greater degree of definition. It is a simple and intuitive tree structure that allows both the visitor to the specialist scholar to focus on portions too small and detail of the product, without losing sight of the general configuration of departure.

To make feasible a further degree of usability of information, the system has been implemented with image viewers metrics in high definition. The images produced are a fundamental basis, strictly from the point of view of science and technology, for the conservation, management and enhancement of the historical and artistic heritage. The case study investigated is the Chapter House of Santa Maria Novella in Florence.
