The purpose of this paper is to present the modern topographic measurement technologies and the evolution towards a new method, that of measurements made with the help of Unmanned Aerial Vehicles (Unmanned Aerial Vehicle - UAV). Photogrammetric measurements were carried out using the DJI Phantom 4 Pro drone, which made it possible to learn a new way of working, much faster and more efficient, compared to traditional topographic measurements. The research presented in this paper was carried out in the western part of Romania, on the administrative territory of Timiș County, on the campus of the "King Mihai I" University of Life Sciences in Timisoara. The use of drones in the field of geodesy is currently in high demand due to its relatively easy operation and relatively affordable cost compared to satellite systems, especially high-resolution images. Over the past decade, the use of unmanned aerial vehicles as remote sensing platforms has become increasingly popular for a wide range of scientific disciplines and applications. Currently, many photogrammetric mapping methods use this technology to retrieve and record data about objects on the ground. This is due to the fact that using a drone equipped with GNSS (Global Navigation Satellite System) technology for aerial measurements is very efficient and cheap and allows flying over hard-to-reach areas, significantly reducing the execution time of the work.
