Abstract
Southern Kyrgyzstan is a region of high landslide activity that frequently endangers human lives and infrastructure. So far, precise spatio-temporal information on landslide activity has been limited, although landslide occurrence in this area has been investigated for the last 60 years by local authorities. The establishment of a comprehensive landslide inventory is a prerequisite for carrying out objective landslide hazard assessment. For this purpose, multiple sources of information about slope failures are analyzed with the goal of establishing a spatially and temporally consistent multi-temporal landslide inventory at a regional scale. In this context, the potential of satellite remote sensing and GIS based analysis is investigated. The paper describes the developed approach for multi-source landslide mapping and demonstrates its application to the Budalyk valley test site.
