Acquisition of Photogrammetric Data Using Uav – Case Study: Bistriţa Limestone Quarry, Vâlcea

Through this paper the project team aimed to demonstrate the utility and feasibility of using flights and photogrammetric methods in surface mining in mountainous areas. Thus, in the first part of the paper, the working principles, the applied methodology, the criteria for selecting the methodology, and the necessary resources are presented, and later the results obtained from the case study from the limestone quarry in Bistrița, Vâlcea are presented. At the same time, the environmental, relief and accessibility conditions in the mining perimeters were identified and practical recommendations were issued regarding the execution of a photogrammetric data acquisition flight in the surface mining operations in the mountain area. This paper indicates risk factors identified in quarries in the mountain area and offers practical solutions to avoid them.
