UAV-BASED SURVEY: THE CASE OF COLONIA VARESE IN MILANO MARITTIMA

Abstract. The Maritime Colonies are an important part of Italy's cultural heritage buildings. The research focuses attention on a survey with an Unmanned Aerial Vehicles (UAV), using photogrammetry to determine features such as dimensions, object shape, volumes, areas, distances, elevations, and set up the reconstruction of a digital model of the Varese Colony, located in Milano Marittima, in the province of Ravenna. To digitize this structure, it was necessary to use a camera network capable of creating nadir and oblique images with different baselines. The proposed method has proven convincing in real-world application because of its workability, easy implementation, area coverage, and can be used in a wide range of applications on artifacts of many different morphologies.
