THE USE OF UAV DATA FOR PHOTOGRAMMETRIC DOCUMENTATION

Photogrammetry is a rapidly developing field of science, using new technologies such as unmanned aerial vehicles (UAVs) and digital cameras. Currently, unmanned aerial vehicles are not only used for amateur or professional commemorative aerial photos, but also have much more specialized applications. New technologies allow for faster development of numerous fields of science and provide better results with less work and resources. Unmanned aerial vehicles are used for photogrammetric raids, which produce photogrammetric images of terrain surface or buildings. This allows the generation of orthophotos, and even three-dimensional terrain models, enabling further analysis of a research area. The aim of the study was to make an orthophotomap of the cemetery in the Sułoszowa municipality on the basis of data obtained during a drone raid and to compare it with the existing orthophotomap. The goal was planned to be achieved through the following steps: importing images to Agisoft PhotoScan and georeferencing them to ensure metricity of subsequent studies, generating an orthophotomap and a cloud of points mapping the studied area, compilating and comparing the resulting numerical data, as well as graphic data.
