Potential of Using Unmanned Aircraft Systems for Landslide Monitoring: the Case of Janowiec Landslide in Poland

One of the first visible signs of landslide occurrence is changes in microrelief of the slope. In the classical landslide monitoring procedure to determine the land deformation, direct surveys are used. To get accurate and actual information about the object, the ultrahigh resolution unmanned aerial systems imagery can be applied. A digital surface model can be developed and utilized to create a high-resolution orthophotograph as well as a point...
