Sar Interferometric Point Target Analysis and Interpretation of Aerial Photographs for Landslides Investigations in Ticino, Southern Switzerland
نویسندگان
چکیده
Information on landslide displacement from SAR Interferometric Point Target Analysis (IPTA) and sketch maps from aerial photography interpretation are combined for the study of landslides in Ticino, Southern Switzerland. Numerous unstable phenomena are considered in this mountainous region, with an elevation range from approximately 200 m a.s.l. to more than 3000 m a.s.l. The results achieved with IPTA are attractive to complement aerial photographs interpretation for the evaluation of the state of activity of landslides over villages and in sparsely vegetated areas with numerous exposed rocks. On the other hand, over vegetated areas (forests and meadows) IPTA failed to retrieve displacement information.

Interpretation of Aerial Photographs and Satellite SAR Interferometry for the Inventory of Landslides
An inventory of landslides with an indication of the state of activity is necessary in order to establish hazard maps. We combine interpretation of aerial photographs and information on surface displacement from satellite Synthetic Aperture Radar (SAR) interferometry for mapping landslides and intensity classification. Sketch maps of landslides distinguished by typology and depth, including geo...

A variation of the landslide activity is expected according to the climate change in the Alps, especially in permafrost environment. Mountain areas are not very well controlled by monitoring systems due to the high costs. Therefore, satellite data and especially repeatpass SAR interferometric techniques are an important option for the monitoring. In our contribution differential SAR interferome...

An advanced SAR interferometric analysis has been combined with a methodology for the automatic classification of radar reflectors phase histories to interpret slope-failure kinematics and trend of displacements of slow-moving landslides. To accomplish this goal, the large dataset of radar images, acquired in more than 20 years by the two European Space Agency (ESA) missions ERS-1/2 and ENVISAT...

This paper addresses the local incidence angle dependence of several polarimetric indices corresponding to landslides in forested areas. Landslide is deeply related to the loss of human lives and their property. Various kinds of remote sensing techniques, including aerial photography, high-resolution optical satellite imagery, LiDAR and SAR interferometry (InSAR), have been available for landsl...
