Today, many photogrammetric mapping methods have used drones to retrieve and record data about objects on earth. This is due to the fact that the use of a drone equipped with GNSS (Global Navigation Satellite System) for air measurements is very efficient and cheaper compared to renting an aircraft, it also allows flying over hard to reach areas and significantly reduces of the work. The development of UAV technology in Romania is still in its infancy, and the legislative framework is extremely restrictive, even for small drones, which significantly affects the expansion potential of this field. UAV equipment must be registered and a fee must be paid that sometimes exceeds the value of the equipment. Thus, in order to use the aircraft, you need approval from the Romanian Civil Aeronautical Authority as well as an approval from the Ministry of National Defense. Flights are limited in distance, altitude and area, and requests must be submitted at least 20 days prior to the flight. The rapid development of new technologies nowadays offers the possibility to acquire high-resolution topographic data that can serve as a basis for digital analysis of the terrain. This paper presents the results of the application of UAV photogrammetry data in the mapping of Labasint locality from Arad county, using a WingtraOne VTOL tailsiter drone, equipped with a Sony RX1RII camera with a 42.4 megapixel CMOS sensor, 35 mm, fullframe and a high precision GNSS system. The use of drones in geospatial science is currently in high demand due to its relatively easy operation and relatively affordable cost compared to satellite systems, especially high-resolution images. One of the benefits of using drones is that they take aerial photographs that are then processed for mapping so that they can be used to support the acquisition of spatial data. The final stage of data processing includes the generation of orthophotoplanes, mosaics, raster images, TIN and DEM formats as well as the generation of point clouds.
