DTM to NURBS-A parametric approach to landscape modeling

The aim of this research work is the automated generation of a three-dimensional Nurbs model from a series of data on a territorial scale. The difficulty of working with this type of procedure is the sectorialisation of technical skills among the technicians who deal with design at the architectural scale and those who works at territorial scale. The undertaken methodology is to establish a workflow that can export data from a GIS tool and import it into a three-dimensional modeler. To do this you need an intermediate tool, a parametric software. The explained procedure aims to have maximum freedom of processing of model geometries; therefore, the geometry has been based on Nurbs mathematical models. The case study where the methodology of this research has been applied is the territory of Ortona, Italy, the Adriatic coast. Starting from the cartographic data of the Abruzzo Region, the three-dimensional model has been realized as in the forecast. This working methodology ensures efficient results with a low amount of human iteration to generate the final model. Some of the limitations of the procedure have been explained in detail, mainly due to the structure of the used components .
