The disciplines included in this sector are Geodesy (physical, geometric and spatial), Topography, Photogrammetry (aerial and terrestrial), Cartography, Remote sensing (by satellite, airplane and close-range), navigation (space, air, sea and land) and Geographic Information Systems. The application areas concern, in particular, the study of the global and local reference systems, the instruments and methods of detection, control, monitoring of the territory, of the structures and cultural heritage, the processing of measurement data, the production and updating of cartography, topographic DBs, layout of works and infrastructures, mobile systems for surveying, digital terrain and surface models, management and sharing of multidimensional and multi-time geographic information.
