Impiego di tecniche geomatiche integrate per lo studio di aree glaciali e recentemente deglacializzate delle Alpi Occidentali piemontesi

The purpose of this work is to present the methodologies applied to study dynamical areas, as glacial and periglacial areas. The working group is composed by members of Turin University (GeoSitLab laboratory) and the CNR-IRPI Torino, in the framework of the Interreg Alcotra n.56 project GlaRiskAlp (Glacial Risk in Western Alps). The methodology exploits digital aerial photograms, that are orthorectified, to extract themes for a topographical and geomorphological characterization of landscape at regional scale. At a local scale, the DEM extraction, from flights of different years, is useful to make comparisons of glaciers surface. Remote sensing techniques are doubtless necessary in large or unaccessible areas, but they are integrated by GNSS campaigns on field, using a fixed GPS station, and a kymatical one, to obtain topographical profiles of glacier variations.
