Estimate of the 3D kinematics of an Alpine glacier by merging terrestrial radar interferometry and image cross-correlation

We present a new methodology for coupling two distinct and independent datasets to estimate the 3-dimensional surface kinematics of an Alpine glacier. These datasets were collected by different remote sensing systems that can measure complementary components of the surface motion vector. The method was applied to the data acquired during the monitoring campaign of the Planpincieux glacier (Italian side of the Mont Blanc massif) carried out on 4-27 September 2015 with a ground-based SAR (GBSAR) and a monoscopic visual-based system (VBS) equipped with two SLR cameras with different focal length. Overall, we collected and processed more than 2300 radar images and 300 photographs.NO ACKNOWLEDGEMENTS
