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

Table 1

Main characteristics of the analyzed datasets; Asc: ascending; Desc: descending.PS density was calculated with regard to the extent of the AOI, which was equal to 0.11 km² for the Pitigliano cliff and 1.73 km² for the territory of Bivigliano.
