The purpose of the work was to perform scanning and determination works of the roof of the Timișoara Metropolitan Cathedral, a building included in CF 447217 Timisoara by performing a drone flight to visualize the current state of its roof and create a 3D model. The architectural concept for the Orthodox Cathedral in Timișoara is in the Moldavian style, creatively processed with several different influences, of which the Gothic style is predominant. The buildings, belonging to this style, present a completely different architecture from that of other Orthodox buildings in Timișoara, built in the interwar period. The construction itself is also characterized by the ample play of roofs. The cathedral building contrasts harmoniously with the great triumphal arch of the Timișoara Opera, creating a plastic tension, which brings new scenic values to the urban space in Victoriei Square. Several phases were completed, so the identification of areas was performed and topographic strategies were established. In the information gathering phase, a topographic survey was performed with the help of GPS-RTK GNSS technology, in order to perform the drone flight. The data processing and the elaboration of the documentation was done with specialized computer programs specific to UAV technology, respectively Agisoft, transcalculated in Stereo 70 projection. The steps used are part of the methods used in the work of all profile offices, high-performance high-performance equipment for state-of-the-art field work for the execution of data retrieval, as well as for post-processing of data in order to accurately perform the final work. This ability to perform rapid spatial analysis provides both a qualitative and quantitative advantage by being on an upward slope and expanding use in various fields of activity. The most important qualities are the possibilities of automating works in the field of spatial analysis compared to graphically oriented systems: computer graphics processing. These possibilities of automating such works allow geographic reference data to be created and used in different fields of activity.
