The diploma thesis deals with the use of unmanned monitoring in conditions of precise agriculture. The literature review provides information on the distribution of drones from a technical point of view, information on precision farming, geographic information systems and plant monitoring, and on the use of unmanned aerial vehicles in the Slovak Republic and the Czech Republic. The own work is focused on the statistical processing and evaluation of data usable for work in the ArcMap program and the economic evaluation of the efficiency of the use of unmanned aerial surveillance in the conditions of precision farming.
