This article examines the possibilities and the effectiveness of such devices to obtain images during mass events at various time intervals. The aim was to design a visualisation of the dynamics of change in the number of participants of mass events. At the same time, the paper presents an attempt to systematise the process of acquiring data using this type of Unmanned Aerial Vehicle (UAV).polinfo:eu-repo/semantics/openAccessdronesBSLUAVRPAmass eventsArtykułhttps://doi.org/10.14746/bfg.2015.6.12
