Shallow landslides are generally triggered by intense rainfalls of short duration. Even though they involve only small portions of hilly and mountainous terrains, they are the cause of heavy damages to people and infrastructures; the identification of shallow landslide prone-areas is, therefore, a necessity to plan mitigation measures. Stereoscopic analysis of photogrammetric products is generally the most used technique for mapping landslides, specially if combined with intensive field surveys. The new generation of high resolution satellites presents resolutions ranging from 0.5 to 2 m, offering a baseline for a quick and accurate update of regional inventory maps. In this paper we discuss the application of Pleiades images for rainfall triggered shallow landslide mapping.

Abstract
Shallow landslides are generally triggered by intense rainfalls of short duration. Even though they involve only small portions of hilly and mountainous terrains, they are the cause of heavy damages to people and infrastructures; the identification of shallow landslide prone-areas is, therefore, a necessity to plan mitigation measures. Stereoscopic analysis of photogrammetric products is generally the most used technique for mapping landslides, specially if combined with intensive field surveys. The new generation of high resolution satellites presents resolutions ranging from 0.5 to 2 m, offering a baseline for a quick and accurate update of regional inventory maps. In this paper we discuss the application of Pleiades images for rainfall triggered shallow landslide mapping.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
