Abstract. The research work, object of this paper, is included in the "Fragile Territories" project of the Department of Architecture and Urban Studies of the Politecnico di Milano. It addresses the problem of mapping a territory, starting from the case studies of this issue in the contemporary scientific literature and trying to solve them by available raster/vector GIS database. The first innovation introduced with this research is the coding of an algorithm which takes as input the vectorized points from GIS and associates them with the heights transformed into z coordinates. The result is a three-dimensional grid of points. This grid is the basis for the creation of a single NURBS surface that will become the basis for the projection of all vector entities exported from the GIS into the modeler. In doing so, the result of the operation is a three-dimensional georeferenced NURBS model that contains all the vector entities in the territorial database.
