Rapid Mapping and Deformation Analysis over Cultural Heritage and Rural Sites Based on Persistent Scatterer Interferometry
Figure 9
Spatial distribution and related field for the ENVISAT ascending (2003–2010) dataset over the central-eastern part of the Pitigliano town centre. Localized deformation is identified over some buildings, with downwards moving PS showing a progressive LOS displacement trend away from the satellite (a), while one downwards moving PS and some apparently stable PSs located close to the cliff edge share a common LOS displacement trend, especially since February 2007 (b).
