Abstract

With this research work, the aim is to structure an innovative modus operandi aimed at representing a territory with a multi-scalar approach, consistent with vector modelling, which allows to make analysis from an urban and architectural point of view in a synergistic way. The data at the base of this system are GIS type, therefore georeferenced, associated with geometric primitives. The intuition lies in the elaboration of three-dimensional vector models of even very large portions of territory, realized through a visual scripting digital tool (Grasshopper) and processed in a NURBS modeling software. At this stage of the research the attention is mainly focused on the faithful representation of the territory. The case study presented is Arischia, historical center of the province of L'Aquila, located at the foot of the Abruzzo Apennines. For the realization of the model we start from geotiffs of the DTMs that are vectorized in order to get a three-dimensional grid of points that is used to create a NURBS surface that represents the orography of the territory, roads and buildings. The use of NURBS mathematical surfaces allows to lighten the computational burden, obtaining these results in a very short time. The criticality of this methodology is mainly inherent in the availability of accurate spatial data and in some manual operations to make the procedure work. Further development of this work will be the use of remote sensing for perceptive comparison between these two methods of representation.
