Intervenciones virtuales en un entorno urbano: la recuperación de la trama viaria del "call", barrio judío de Girona

Abstract

The Call of Girona, its Jewish quarter, is one of the most important monumental assemblies of Catalonia and by its level of conservation, from across Europe. It characterized by their narrow alleys, heirs of the Roman plot of the Gerunda original, along with the remainder of the old helmet of the city, they configure themselves as the most important historic-urban center of Catalonia. The growing affluence of tourists, along with the successive improvement and ordering of the dwellings and singular buildings that configure the neighborhood, completely inhabited and full of life, is giving a series of urban development measures to improve the accessibility to the same one, at the same time that their residential use is consolidated and of equipment, by means of a regulation of special urban development protection. On the other hand this city has an extraordinary system of information online that permits to have all the urban cartography of the same one and even of a model of Virtual cartographic reconstruction developed by a team of experts under them you promote of the City Hall of Girona and the Museum of History of the City. Taking as environment this zone and information, the development of an investigation applied inside the environment of the architectural graphic expression is proposed, founded first in a work of analysis and study of the bibliographical, cartographic and historic sources in matter of historic-urban development of the zone and in second place, in a study of application of the modern techniques of representation SBIM Sketch Based Interface and Modeling and the Augmented Reality. Melting all these registrations and fields of work, the hypothesis is thrown that is possible to expand the plan of at present existing alleys by means of the cataloguing and lifting of two new alleys, that will call 1, or "d' Hernandez", that we propose to rename as that of the Last Synagogue and 2, or "De les Dones", to date only documented to level of location but that with our work of field and contribution has been seen that they are perfectly recoverable. This recovery is undertaken in the investigation, by means of the visual simulation of the same using the techniques of SBIM and AR, before cited, of form combined and adapted to the specificities of the work and abilities of an architect-town planner, so that they develop a practical study cases series whose final objective is that a visitor, situated before the current entrance walled of the alley, by means of a device type Tablet PC connected to a webcam, can be get an idea of which would be the aspect of that alley, on the other hand inaccessible, given that at present is found walled. This strategy of pre-viewing, should serve besides so that the designer can present the possible alternatives to his not always evident, physical recovery. In that sense and as the architects we propose an architectural solution in each case along with the information devices trial on the land that facilitate the accessibility to the different monuments and hereditary buildings of the historic center of Girona. On the other hand as educational of architectural graphic expression, we practice new strategic graphic that permit to promote the creativity and as a group to facilitate the investigators data processing data and experiences that permit to optimize the new tools and processes, and to the architects in general, to bring to light the current possibilities in matter of SBIM and AR.
