Detecting Landslide Activity by Sar Interferometry
Operational monitoring of slope instabilities by SAR Interferometry poses a number of challenges due to the limited spatial extent of the landslide areas and rainy conditions usually associated with mass movement events. In this work we present the results of the application of both conventional DInSAR techniques, and a point-by-point, multitemporal study of the long-term stability of selected ...
متن کاملEpisodic Landslide Movement in Iceland Studied Using Sar Interferometry
While there is abundant geomorphologic evidence for landslides in Iceland, it is in most cases unknown whether or not these landslides are actively creeping. Here we use Interferometric Synthetic Aperture Radar (InSAR) to assess its monitoring capabilities on three landslides that are known to be creeping and to survey large areas in East and Central-North Iceland in search for other creeping l...
متن کاملEngineering Geology Landslide Investigations and SAR Interferometry
We can distinguish three phases of using the SAR and other EO satellite data in landslide studies: 1. Surface characterisation, ie initial topographic and geomorphological classification, DEMs, photogrammetry (using Spot and Landsat); 2. Measurement of slow to extremely slow slope movements by means of SAR interferometry; 3. Systematic monitoring of temporal-spatial variations in some slide pro...
متن کاملLandslide Classification Using Lidar-derived Data and Spot Imagery
Using spectral-only information for landslides classification is usually confusing with houses, roads, and other bare lands because these ground features have similar spectral patterns on images. In this study, 3D airborne LiDAR data are integrated with SPOT images for landslide classification for improving classification accuracy. A study area is selected in a subbasin of Shimen Reservoir. SPO...
متن کاملRecent Landslide Movement in Tsaoling, Taiwan Tracked by TerraSAR-X/TanDEM-X DEM Time Series
The Tsaoling Landslide in Taiwan has captured attentions of researchers worldwide due to its frequent catastrophic failure and distinctive features. Thanks to the launch of TerraSAR-X/TanDEM-X (TSX/TDX) constellation, retrieval of global DEM with high spatial resolution and accuracy becomes possible, which is extremely useful for the study of natural hazards (e.g., landslides) globally. We atte...
