Abstract. Methodologies and procedures in processing gained data vary based on possibilities and needs of scientific projects. This paper should help to get a general overview in the choice of small unmanned aircraft systems (sUAScommonly known as drones) for scientific purposes, namely remote sensing of geomorphologic processes such as soil degradation in high mountainous areas that are hard to access and have unfavourable weather conditions. All high mountain areas in European countries are legislatively protected, and so various permissions and observation of strict procedures are needed in order to not have a negative influence on the environment. Nowadays, several types of UAS exist that could effectively help us in such protection, as well as in fullfledged utilization when answering scientific questions about the alpine lake genesis. We demonstrate it here with selected examples of our photo documentation.

Abstract. Methodologies and procedures in processing gained data vary based on possibilities and needs of scientific projects. Technology moves ahead very fast. Application of different patents and remote control mechanisms has higher usage not only in military sector, but also in civil sector. These papers should help to get general overview in the choice of "small unmanned aircraft systems" (sUAS or commonly known as drones) for scientific purposes, for example remote sensing. Geomorphologic processes and the development of high mountain area are difficult for mapping and research with respect to accessibility of explored surface, slope of terrain, and mainly weather conditions that are rapidly changing. All high mountain areas in European countries are legislatively protected, and so various permissions and observation of strict procedures are needed, in order not to contaminate or not to have a negative influence on the environment. Nowadays several types of UAS and operating systems exist that could effectively help us in such protection, as well as in fully-fledged utilization when answering scientific questions.
