MAPPING OF A ROCKFALL SITE WITH AN UNMANNED AERIAL VEHICLE

Rockfall, which is a frequently seen disaster at mountainous regions, gives damage to residential areas and transportation corridors. A combination of geological, topographical and climatic conditions cause mass movements. Rockfall barrier design is being designed to capture falling rocks worldwide.  The classical method applied in rockfall analysis is 3D modelling of the study area to determine rockfall trajectory. Digital surface model insert ignore into journalissuearticles values(DSM); of the study area needs to be accurately determined to design barrier system. Unmanned aerial vehicle insert ignore into journalissuearticles values(UAV); can be used to prepare actual DSM from inaccessible areas. In this study, we prepared the DSM of the area affected from rockfall with using a UAV.
