Land subsidence affects many areas of the world, posing a serious threat to human structures and infrastructures. It can be effectively monitored using ground-based and remote sensing techniques, such as the Global Navigation Satellite System (GNSS) and Interferometric Synthetic Aperture Radar (InSAR). GNSS provides high precision measurements, but...
The study of ancient buildings and architectural complexes starts necessarily from a detailed and geometrically correct graphic documentation of their state of conservation that allows a complete analysis and understanding of their planar and volumetric development, as well as of their structural, material and constructive features. This is the cas...
Mass movements represent a serious threat to the stability of human structures and infrastructures, and cause loss of lives and severe damages to human properties every year worldwide. Built structures located on potentially unstable slopes are susceptible to deformations due to the displacement of the ground that at worst can lead to total destruc...
In the mountain environment, the presence of fractures or degradation in the rock mass could represent an important risk both for the safety of population and for the anthropic structures that have a productive, touristic and/or historical importance. For this reason, the monitoring is a primary action of control and risk mitigation. In this work a...
3D survey methodologies are widely applied to the Cultural Heritage, employing both TLS and close-range photogrammetry with SfM techniques. Laser scanning produces models with high metric reliability and accuracy, whereas the main quality of the 3D photogrammetry is the result in term of photorealistic representation. Many studies have been conduct...

Geomatic approaches were used to investigate a landslide in the Emilian Apennines in northern Italy which occurred during excavation works for high-speed railway tunnels between 2002 and 2007. The landslide damaged three buildings located on the upper part of a hillside. At the site of interest, the high-speed railway system included three contiguo...
Subsidence in a deformation area can be measured in various ways, examples being conventional high-precision leveling, differential InSAR and multi-temporal GPS surveys. Integration of methods can improve results, and is crucial to extract high-precision data. In particular, orthometric and ellipsoid elevations, surveyed at different moments in tim...
The safeguarding of Venice and the Venetian lagoon (Italy) from rising water is of great national interest. Besides the normal tidal regime, the effects of an increase in the frequency and intensity of floods in the lagoon have been accentuated by a reduction in the elevation of the land in respect to the actual average sea level. With the aim of r...
Three-dimensional methodologies as Terrestrial Laser Scanning (TLS) and digital photogrammetry, are used to extract digital models of surfaces. In this paper, the two different approaches, integrated with classical topographic methodologies, were applied in the 3D survey of a portion of Phaistos Palace in Crete island. The archaeological site repre...
Laser scanning methodology which has been used in different sectors, allow surveying an object by means of very dense and accurate point clouds acquisitions. The alignment and co-registration in a defined reference system allow generating a D model of the object, with the possibility to associate the radiometric information useful in many applicati...
