    Land movement detection from terrestrial laser scanner (LiDAR) analysis
    (SPIE, 2021) Pesantez Cabrera, Pamela Carolina; Pesantez Cabrera, Pamela Carolina
    At the beginning of 2018 a landslide was triggered in the Reina del Cisne (Cuenca - Ecuador) following the cut that was applied to a hillside for the construction of a small access road. From May to June 2018, the period of analysis of this work, the landslide has caused structural damage to several homes, deterioration of a field and the total collapse of the road that caused it. Field visits and the comparison of point clouds obtained with a terrestrial laser scanner (LiDAR) in the months of May and June 2018 have highlighted the high activity of this landslide. This article introduces the process that was performed to compare the point clouds obtained. The results show the feasibility of using terrestrial laser scanner (LiDAR) for early detection of landslides.

    Land movement detection from UAV images
    (Publicaciones ISPRS, 2022) Pesantez Cabrera, Pamela Carolina
    In Reina del Cisne (Cuenca-Ecuador) a dynamic sliding process was created due to a cut that was applied at the beginning of the year 2018 to the hillside without technical considerations for the construction of an access road to a house in the sector. From January 2019 to June 2019, period analyzed in this work, the landslide has caused total structural damage (dwellings near the hillside) or partial (houses away from the hillside) and the total collapse of the path that caused the landslide. The field visits and the comparison with CloudCompare of the clouds of points obtained by flights of an unmanned aerial vehicle, UAV between the months of January 2019 and June 2019, have highlighted the high activity of this landslide. The resulting analysis clearly presents the applicability of this technique for early detection of landslides.
