Abstract


I sistemi laser a scansione terrestre caratterizzati da una lunga portata, cioè capaci di rilevare su  distanze  fino a 3 km, sono oggi sempre più utilizzati nel monitoraggio del territorio e nel controllo del dissesto o, in generale, delle variazioni morfologiche.

 

Laser scanning survey of landslides by means of long distance ILRIS LR

Terrestrial laser scanning (TLS) is a remote sensing technique for high density acquisition of the physical surface of scanned, currently used in geologic surveys, engineering practice, cultural heritage, and mobile mapping. The very long range scanners, allow the acquisition from distances of the order of about 1  km  with  material  characterized  by  medium/high  reflecting properties.  At  present,  the  efforts  in  technological  advancements are highly aimed at the extension of maximum range, at the reduction of acquisition time, and so on. The ILRIS LR laser  scanner,  provided  by  Optech,  is  used  to  survey  a  very dense populated landslide area in the Tuscany Apennines, in the frame of a scientific experiment planned by INGV to test its performances.
