In recent years, there has been a rapid development of SAR acquisition techniques and all new satellite radar missions are equipped with SAR devices allowing beam steering. This paper presents results of experimental application of TerraSAR-X in ultra-high resolution SpotLight and Staring SpotLight modes for the area of the Just landslide in the Rożnow lake area. Another analyzed example was to use data of the medium resolution Sentinel-1 data acquired in the TOPS mode for the Huciska and Zapadle landslides in Szymbark. In this case, a network of 12 radar reflectors (corner reflectors) was installed to make the results independent of vegetation conditions on landslides. This study presents preliminary results of measurements and discusses the potential of applications and directions of further work.

Mass movements are a major problem associated with the sustainable planning of space. They often cause permanent degradation of the areas of development or agricultural use. Exclusion ofactive landslides and periodically active landslides from development area is obvious. Restrictions on land use areas of active and inactive landslides and their buffer zones involve differences in opinions. A useful tool in the assessment of risk of landslide in such areas can be a low-cost system LandSMS (LandSlide Monitoring System). The prototype of the system consists of a sensing element (tie-rod), a monitoring station and a data server. Tie-rod is attached to the concrete slab, which is stabilized on the landslide area. Surface deformations resulting from movement of the landslide are controlled by two sensors - encoder and an ultrasonic sensor. The system operates continuously. In the case of an emergency situation system informs authorized persons about the incident. Efficiency and system functions are analyzed on a selected area of the landslide in Klodne (Little Poland, commune Limanowa). Preliminary results confirm the usefulness of the system. In the initial observation period (October-December 2016) displacement reached 8 mm. This is due to stabilization of the measuring point. Later, there was no displacement effected by mass movements reported.
