| Zusammenfassung |
| The aim of this work is to analyse the advantages and disadvantages
of using the new X-band SAR data acquired by TerraSAR-X
sensors for landslides mapping. This dataset has been processed
using a Persistent Scatterer Interferometry technique over the Upper
Tena Valley (Central Pyrenees, Spain). In the first section, the
geological and geomorphological setting of the study area is
introduced, focusing on the description of the landslide inventory.
Then the Stable Point Network technique is briefly described,
followed by the assessment of the performance of the X-band
SAR dataset. In this context, we present first a model to predict
the distribution of Persistent Scatterers based on the slope
geometry and the land use information, which has then been validated
with X-band data results. On a second stage, we have assessed
the performance of X-band dataset to detect and monitor
mapped landslides. Finally some illustrative case studies are shown
demonstrating the potential of using X-band SAR data not only
for landslide mapping but also to detect and monitor deformations
affecting human infrastructures. |
