Fig. 8From: Spaceborne, UAV and ground-based remote sensing techniques for landslide mapping, monitoring and early warningOptical images of the unstable rock masses of the western Elba coastline (a = M1; c = M2; e = M3); related 3D digital model with the detected basal and lateral slipping planes (b, d, f); mosaicked thermograms from IRT (g = M1, h = M2, and i = M3) acquired around 1 p.m., November 2011 (dotted lines mark the basal slipping planes; white squares on the thermogram allow a comparison with the correspondent sectors in the optical images, acquired by the built-in digital camera) (modified after Gigli et al., 2014a)Back to article page
