This paper presents an improved approach of multi-temporal interferometric synthetic aperture radar (InSAR) for detecting land subsidence phenomena by using time series of high resolution SAR images. Our algorithm extends the capability of the temporarily coherent point (TCP) InSAR technique proposed previously to detect subsidence even in the case of a small number of SAR images available for ...

This paper presents preliminary results of the application of Persistent Scatterer SAR Interferometry for landslide mapping support. The PSI data were obtained basing on ERS-1/2 SAR data for the part of Carpathian Mountains in southern Poland. Careful PSI data processing allowed achieving very reliable results that were verified during the detailed field mapping. PSI data present their high app...

Displacement time series (TS) provides temporal and spatial information related to ground deformation. This study aims investigate behavior of deformation TS, including classification displacement trends periodicity evaluation, which ease the interpretation movements. To this end, we propose several modifications an existing automatic workflow Persistent Scatterers Interferometry (PSI) TS using...

Earthquakes cause a huge number of landslides and alter the regional landslide risk distribution. As result, after significant earthquake, susceptibility maps (LSMs) must be updated. The study goal was to create seismic containing causative variables which are adaptable great changes in Jiuzhaigou earthquake (MS 7.0) perform rapid update LSM by means distributed scatterer interferometric synthe...

This study proposes modifications to an existing automatic classification method of Persistent Scatterers Interferometry (PSI) time series (TS) and a new procedure classify ground movements into seven classes. We also represent technique detect TSs affected by phase unwrapping errors reclassification part stable points, which are incorrectly classified as moving points using the original method...
