Mapping slope movements in Alpine environments using TerraSAR-X interferometric methods

Barboux, Chloé ; Strozzi, Tazio ; Delaloye, Reynald ; Wegmüller, Urs ; Collet, Claude

In: ISPRS Journal of Photogrammetry and Remote Sensing, 2015, vol. 109, p. 178–192

Mapping slope movements in Alpine environments is an increasingly important task in the context of climate change and natural hazard management. We propose the detection, mapping and inventorying of slope movements using different interferometric methods based on TerraSAR-X satellite images. Differential SAR interferograms (DInSAR), Persistent Scatterer Interferometry (PSI), Short-Baseline...

The New swiss glacier inventory SGI2010: relevance of Using high-resolution source data in areas dominated by very small glaciers

Fischer, Mauro ; Huss, Matthias ; Barboux, Chloé ; Hoelzle, Martin

In: Arctic, Antarctic, and Alpine Research, 2014, vol. 46, no. 4, p. 933–945

In view of the rapid and accelerating glacier retreat observed in the European Alps during the last decades, the repeated creation of glacier inventories is important to understand the spatio-temporal variability of glacier changes and to support modeling studies. This article presents the latest glacier inventory for the entire Swiss Alps (SGI2010) derived by manual digitization from...

Inventorying slope movements in an Alpine environment using DInSAR

Barboux, Chloé ; Delaloye, Reynald ; Lambiel, Christophe

In: Earth Surface Processes and Landforms, 2014, p. -

Differential SAR Interferometry (DInSAR) is a technique that can be used to detect and characterize slope movements. It is investigated here as a tool for establishing a detailed overview of complex slope movements at a regional scale in an Alpine context. This paper gives specific recommendations to use and to understand DInSAR signals in mountainous areas located above the tree line, excluding...
