Garzeno test site: PS velocity map of the large unstable slope obtained by processing CSK SAR data acquired on ascending pass (a), ENVISAT ASAR data acquired on ascending
pass (b) and ENVISAT ASAR data acquired on descending pass (c). Background optical image is from GE. Yellow and white rectangles enclose, respectively, the overall failed slope
and peri-urban slide toe areas used to compute the PS spatial densities reported in Table 2. Black lines indicate positions of three profiles (AB, CD, EF). The inset figures (d), (e) and
(f) show variation in average LOS of PS velocities (in mm/yr) along profiles AB, CD and EF, respectively, derived by using (from the top to the bottom) CSK ascending, ENVISAT ASAR
ascending and ENVISAT ASAR descending dataset. The height variation along the profiles (shown at the bottom of each inset plot) are based on SRTM data.
