The idea of the Chart of Urban Transformations originated from the need to have at disposal a communication channel with the city, in order to talk about the development of particularly relevant and complex projects, as to the high number of people involved, the importance of the areas and the variety of financing sources.

The goals of the "Chart of Urban Transformations" are on one side the collection and updating of the state of realization of the great urban projects, and on the other side the accessibility and spread of its informative contents, in order to help the participation and the public comparison on the themes of the strategical projects.

The Chart, thought as an informative instrument respect to the characteristics and to the state of realization of complex projects, has been developed in order to use it as an evaluation instrument, as it allows to stress the links intercurring between the different projects and their relationships with goals and policies.

The Chart brings together, in a homogeneous framework of knowledge, the set of informative elements needed for the monitoring, promotion and handling of the great urban projects, both public and private, promoted by the City Council Administration. The informative basis was originally organized on three levels: Urban Projects, Sub Projects, Punctual Interventions.

Each Urban Project is divided into Sub Projects, which too are divided into various Punctual Interventions. These represent the actions through which the policies of territorial transformation are realized. For each one of them are given informations regarding goals, characteristics, dimensions, workers, financing, state of realization, press review. The Chart of Urban Transformations is run by a Geodatabase provided with an articulated and complex relational and informative structure, in which each taken entity is georeferred, thus being readable on the cartographic technical support of the Venice City Council. The Geodatabase has three spaces for data processing and representation:
 a GIS space used for cartographic representation, spatial processing and the creation of thematic tables;
 a relational Data Base space, used for the servicing and processing of the territorial data base;
 a Web space, used for the communication and spread operations through the Internet. Currently, the modalities of explanation of the projects are being reviewed, in order to semplify the access to informations, uniforming to the accessibility standards. Since June 2002, the Chart of Urban Transformations can be viewed on the Internet, in the website “Urban Transformation” www.comune.venezia.it/trasformazioni.

The Chart of Urban Transformations contains now informations relative to 142 projects.
