3D survey for technology transfer: Largo Da Memoria in São Paulo, Brazil

With the broadening of the concept of Cultural Heritage - which now, in addition to great monuments, also includes urban cores, landscapes and intangible manifestations - the possibilities for heritage conservation actions have also expanded. Nowadays, in a globalised world immersed in technologies that are evolving with astonishing rapidity, precisely technological innovation can be an important ally for the enhancement of historic public spaces. On the occasion of the bicentenary of the placement of the existing obelisk in the “Largo da Memória” public space (in the centre of São Paulo), a three-dimensional survey pilot project was carried out in cooperation with local municipality. One of the objectives of this project was to develop an example of “good practices” for the conservation of urban space and a possible benchmark for the use of digital data by local technicians avoiding expansive software and hardware solutions. Thus, the three-dimensional survey of the area helped to evaluate the effectiveness of the optimisation of the integrated procedure, taking into consideration the importance of the public space of the Largo, at the intersection of Xavier de Toledo and Quirino de Andrade streets. Technology transfer actions played an important role within the whole process, enabling further evaluations for the conservation of the place by local authorities.
