Abstract (EDOC: 1341)
In southern Kyrgyzstan extensive landsliding is primarily caused by ongoing tectonic deformation which is superposed by other landslide triggering factors, such as lithological setting, relief, climate and surface cover. The goal is to develop a multi-sensor approach combining analysis of optical (Landsat-TM, declassified US intelligence imagery) and SAR intensity (ERS-1/2) remote sensing data with results from Differential SAR Interferometry in a GIS environment to assess the potential for hazardous mass movements on a regional basis. For this purpose a pilot study area of approx. 100 by 100 km containing a typical variety of landslides was chosen and first field investigations were carried out last summer. Present work is focused on developing techniques for remote sensing based spatial derivation of parameters characterizing main landslide triggering factors in the area. Emphasis is put on a spatially accurate representation of these parameters to create a high quality digital database for further analysis towards a GIS-based regionalisation of typical landslide processes. These investigations support the ongoing monitoring activities of the MECD.
