摘要

The central part of Tyrol (Austria) was hit by a heavy rainstorm on June 7th 2015 which triggered numerous landslides and mudflows in the Sellrain valley. A series of SPOT-5 (Take 5) images from April to September 2015 for the site of Sellrain were tested. A pixel based landslide detection approach was applied in order to evaluate the potential on exploiting 5 days’ time series in a similar way on the soon available SENTINEL-2 sensor. For this work, 13 scenes in total were taken into consideration, but the detection of landslide-induced change on the image data was focused on a pair of images, more precisely the one acquired on the 6th and the 11th of June 2015. This semi-automatic method exploits the geo-processing capabilities of ArcGIS software, so that his use is highly recommended in the context of disaster management.
