Perspectives for a public space. Visualizations visions images.

The research investigates the contemporary urban space structuring through the Drawing and the Survey methods, as places for experimentation and control of the city transformation dynamics. Is assumed as an example the 19th century foundation orthogonal grid of the Bari city which reveals the dynamism of changes taking place on the historical settlement. Starting from the city representation, the visual qualities are analyzed of some main roads that originally constituted the perceptive support of the city spatial unity. The graphic reconstruction, obtained from the street fronts two-dimensional representation and from the public spaces three-dimensional survey, with the use of photomodeling tools and laser scanner technologies, has allowed a deep reading of the visual described aspects. The knowledge process, implemented in the representation space, drives the environment projects towards conscious choices that protect the fragile historic city.
