Unmanned Aerial System (UAS), also known as ‘drone’, has found many applications in various sectors of human activity. Drones were shown useful since they can be used for remote investigations in very simple manner. They can be navigated by the operator from the ground or they can conduct an investigation by themselves in programmed flight path. In the Republic of Croatia, drones have recently been effectively used as part of investigative work for the purpose of design and remediation measures in many landslide areas. Northern part of Croatia is characterized by a large number of landslides which can cause serious damage to buildings and transportation infrastructure, personal injury and traffic delays. In order to detect features linked with landslides (boundaries, cracks, etc.) a drone technology is applied and was shown as very effective, with some examples shown in this paper. Not only that overall cost of the investigation is lower, but ‘bigger picture’ of landslide areas is taken in consideration. Also, increase of safety is also significant since engagement of additional personnel is avoided, which was previously inevitable since they needed to examine ‘dangerous to reach’ areas in order to detect features linked with landslides,
