Abstract
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.

SNAI is a partner of the DAStU Department of Excellence, which intends to promote research and educational activities related to the theme of Fragile Territories, in this case, starting from the Internal Areas (AI)
This set of vectors has been associated with a colour that shows only a selection of the road network of known slope. On this subnet it is possible, using an algorithm, to trace a path that connects the centers with the main nodes of the network, ensuring better accessibility. The value of this parametric system lies in its intrinsic flexibility since once the vector network of georeferenced roads in space has been generated, it is possible to produce threedimensional predictive analyses that are not possible in a GIS, such as inserting elements that attract routes, such as cultural elements or those peculiar to the territory
Summary
A paradigmatic case of this condition is Lanciano city center, which has both the railway station and a line that would connect it with the coast, but both are disused On this territory there is a developing network based on soft mobility, created along the coast by the retreat of the pre-existing railway sediments, in progress at the date of this work, where solutions for slow, active and proximity tourism could contribute to encourage better uses of the territory and to improve its spatial quality. The cycling areas are part of a longitudinal link project which may cross the entire study area, but at the paper drafting stage only a few stretches have been completed Starting from this longitudinal network that is being defined, it is possible to think of extending the connections in a transversal direction, joining the hilly inhabited areas with an enhancement of the slow mobility system, based on the decommissioned railway network already present. The use of traditional GIS tools has been insufficient for a quantitative analysis of the three-dimensional qualities of the case study, so it was necessary to implement ex-novo a series of tools useful for this purpose
