Un modello di rilievo integrato come piattaforma di prefigurazione e controllo delle trasformazioni del territorio. Il progetto di ripristino dell’Aviosuperficie di Piano Tardo (EN)

Every action of transforming the territory is a complex procedure, which must take account of multiple interacting parameters, tied to economic and functional matters, to legislation, to anthropic and natural existing phenomena and interferences, to the nature of the topos, with its potential and critical issues. With the responsibility of determining, at times irreversibly, the destiny of a place, the design process should be tackled with highly sensitive and finely-tuned tools. These must be able to interpret and examine the site with its specific qualities and trigger an osmotic process of filtering information, indispensable for the verification of the coherence of eventual projects with existing anthropic and environmental features. This work seeks to focus on fact-finding strategies implemented for the restoration project of an airfield in the Piano Tardo (EN) district, in synergy with the University of Enna “Kore” and Sicilian Region Forestry Department, for both Civil Protection purposes as well as providing educational and service uses for university activities. The designated area, lying within state property land and formerly used as a military airport during World War II, is at present affected by some infrastructural interferences and irregular woodland vegetation. The aspiration to devise the project in a way to reduce the impact on the place and the preexistences to the minimum, has made it necessary to prepare an accurate survey campaign, integrating 3d laser scanning and GPS technologies, able to indicate, in addition to the planoaltimetric trend, also the infrastructural interferences, underground and aerial, and the quantitative and qualitative consistency of the vegetation involved. The virtual model thus obtained has become the ‘place of the project’, a three-dimensional and georeferenced ‘grid’, on which the readings of several themes have been configured. This represents the mutual instrument for dialogue with all the agencies involved and, above all, the platform for step by step verification and legitimization of the various hypotheses of fine-tuning the project.
