THERMOGRAPHIC CHARACTERIZATION OF A LANDFILL TROUGH AN UNMANNED AERIAL VEHICLE
The use of the thermal imaging camera for Unmanned Aerial Vehicle (UAV) survey is to date very common for environmental analysis, especially if high spatial resolution images are required. Some analyses require images to be acquired close to sunrise, to avoid the influence of the incident solar radiation on the surface temperature, as in the case of a landfill survey. Indeed, thermal anomalies due to generated landfill biogas can be characterized once other heat sources are excluded. In this framework, thermal images need to be processed similarly to optical images by typical photogrammetric workflows producing both a Digital Surface Model (DSM) and an ortho-image. The low spatial resolutio…
Active deformation in a sector of the Sicilian-Maghrebian Chain: new insights from integrated GNSS, structural high-resolution seismic reflection and seismological data
We document active deformation in a sector of the Sicilian Maghrebian Chain exposed in north Sicily and in its offshore prolongation on the basis of the integrated analysis of 1) time series of data collected by GNSS acquisition representing the change in the positions (X and Y) of permanent stations located in Palermo, Partinico, Prizzi, and Termini compared to the IGS station of Noto, 2) high-resolution (Sparker) single-channel reflection seismic data, 3) structural data, and 4) seismological data. The average values for the velocity vectors obtained for the Palermo, Partinico, Prizzi, and Termini Imerese stations are 4.55, 2.97, 2.96, and 2.15 mm/yr, respectively. The direction of the ve…
