Abstract
This study formulates some of the actual problems that arise during engineering and geodetic survey for designing road repair and reconstruction. An analysis of the regulatory requirements currently in force in Ukraine for carrying out this type of work has been carried out, it has also been concluded that at present they do not keep up with the latest technologies. Studied publications describing the use of unmanned aerial vehicles (UAV). Classified navigation satellite receivers are installed on UAVs, for the purpose of determining coordinates. Particular attention is paid to the installation on the carrier of geodetic class navigation equipment using kinematic GNSS (Global Navigation Satellite System) technologies, such as RTK (Real-Time Kinematic) and PPK (Post-Processing Kinematic). These technologies allow us to determine the spatial coordinates of the centers of photos at the time of photographing with centimeter accuracy, which greatly simplifies the adjustment of digital photogrammetric models and increases their accuracy. But the most important advantage is a significant reduction in field surveying, which makes them less expensive and more efficient overall. In the course of the study, it was found that in conditions of limited access to nearby territories, insufficient stability of the results of determining the centers of images can affect the final quality of products. For cases where the maximum achievable accuracy is at the limit of the possibility of photogrammetric technology, the removal of the most critical elements is proposed to be combined by combining aerial photography technologies with ground technologies. The road’s hard surface surveying can be performed by ground geodetic methods (tacheometric or GNSS), and by modern laser scanning. At the same time, the adjacent territory, regarding the shooting of elements of which less stringent requirements are established, can be worked out by aerial photography. In further studies, it is necessary to determine the conditions for achieving the maximum accuracy of UAV photogrammetry.
Keywords: aerial photography, photogrammetry, geodetic survey, reconstruction of highways.
