Rapid Mapping and Deformation Analysis over Cultural Heritage and Rural Sites Based on Persistent Scatterer Interferometry

Figure 6

PS spatial distribution and related 𝑉_LOS field over the Pitigliano cliff for the datasets: (a) ERS descending (1992–2000); (b) ENVISAT ascending (2003–2010); (c) ENVISAT descending (2003–2010). The PSI-based rapid mapping led to draw a map of the conservation criticalities (d), which reports the zoning of the unstable sectors and localized deformation, distinguished from the relatively stable areas.
