Rockglacier and Slope Instability Inventory from differential SAR interferograms and optical imagery, 1998-2016, Northern Tien Shan

Strozzi, Tazio; Caduff, Rafael

Rockglaciers and other periglacial processes were mapped using visual analysis of differential SAR interferograms and satellite optical images (Google Satellite, Bing Aerial) between 1998 and 2016. Every object is assigned a process type (rockglacier, landslide etc.) and state-of-activity. State-of-activity indicates surface deformation rates in cm per year.

The inventory includes so far more than 900 objects over an area of more than 3000 kmĀ².
