Integrated Laser Scanner Techniques to Produce High-Resolution DTM of Vegetated Territory

The paper presents the first part of a research project concerning creation 3D terrain models useful to understand landslide movements. Thus, it illustrates process multi-source high-resolution Digital Terrain Model (DTM) in very dense vegetated areas obtained by integrating data coming from three sources, starting long and medium-range Terrestrial Laser Scanner up Backpack Indoor Mobile Mapping System. point clouds are georeferenced means RKT GNSS points automatically filtered using Cloth Simulation Filter algorithm separate belonging ground. Those interpolated produce DTMs which then mosaicked obtain unique multi-resolution DTM that plays crucial role detection identification specific geological features otherwise visible. Standard deviation residuals varies 0.105 m 0.176 for Z coordinate, 0.065 0.300 X 0.034 0.175 Y. area under investigation belongs Municipality Piuro (SO) includes both town surrounding valley. It was affected dramatic 1618 destroyed entire village. Numerous challenges have been faced, caused characteristics processed data. complexity case study turns out be an excellent test bench employed technologies, providing opportunity precisely identify needed direction future promising results.
