Abstract :
[en] Abstract: The creation of a landslide inventory encompassing multi-temporal information needs high quality and high-resolution data source as well as a good knowledge of the field. Visual image interpretation and field surveys are the prevailing methods for landslide inventory mapping while remote sensing techniques have become a widely used source of information for measuring the topography and deformation of the Earth surface (e.g. Berardino et al., 2002). Semi-automatic image analysis methods based on remote sensing techniques are proposed but their quality lacks behind the expert mappings (Guzzetti et al., 2012). Advance processing of SAR images have proven their ability for: (1) landslide detection and mapping (Farina et al., 2006; Cascini et al., 2009; Guzzetti et al., 2012), (2) process monitoring (Hilley et al., 2004; Zhao et al., 2012), (3) hazard assessment (e.g. Nikolaeva et al., 2014) and (4) risk management (Bardi et al., 2014). ...
