In order to extend relevant progress in the investigation of physical relationships between climate warming, permafrost development, glacier retreat, slope internal deformation behaviour and feedback effects in unstable rock slopes, continuous or regular, periodic, temporally and spatially high-resolution measurement series over long periods of time are required. Previous research results were mostly based on periodic measurements of deformations or continuous point measurements by means of GNSS or total stations in accessible areas of unstable rock slopes. Short and medium-term development trends as well as the internal deformation behaviour including feedback effects remained unexplored. These, however, are of essential importance for the identification of physical processes, the scientific proof as well as the allocation of development trends in connection with temporally and spatially variable, external influencing factors. In most cases, the target objects of the working group are extremely steep rock slopes, which are often inaccessible due to permanent rockfall hazard. This requires the acquisition of an in-situ remote sensing laboratory consisting of a Long-Range Terrestrial Laser Scanner (TLS) as well as ground-based interferometric radars protected against weathering.

为了扩大在气候变暖、永久冻土发展、冰川退缩、斜坡内部变形行为和不稳定岩石斜坡的反馈效应之间的物理关系的调查方面的相关进展，需要长期连续或定期、周期性、时间和空间上的高分辨率测量系列。以往的研究成果大多是基于不稳定岩质边坡可达区域的GNSS或全站仪的定期变形测量或连续点测量。短期和中期的发展趋势以及内部变形行为，包括反馈效应仍然没有得到探索。然而，这些对于确定物理过程、科学证据以及与时间和空间可变的外部影响因素有关的发展趋势的分配至关重要。在大多数情况下，工作组的目标对象是极其陡峭的岩石斜坡，由于永久性落石危险，这些斜坡往往无法进入。这就需要购置一个现场遥感实验室，其中包括一台长距离地面激光扫描仪以及防风化的地面干涉雷达。
