Megjegyzések:	This study discusses the importance of wetland habitats in maintaining hydrological cycles, providing ecological value, and serving as a natural habitat for endangered species. These habitats include oxbow lakes, which are formed by river bends and serve as unique habitats for various plant and animal species. The distribution of these species may depend on direct contact with the river and seasonal flooding events. Oxbow lakes are sensitive to environmental factors, including sedimentation and human activities, which can affect their lifespan and contribute to eutrophication. Remote sensing is a useful tool for studying these habitats, as they can be difficult to access for field surveys. However, existing satellite data may not have high enough spatial resolution for detailed mapping of smaller oxbow lakes, necessitating the use of aerial or unmanned aerial vehicle (UAV) surveys. UAVs offer a more cost-effective and efficient alternative to traditional aircraft surveys, with the potential to capture high-resolution data over smaller areas. We introduced a case study and conducted a UAV survey of the Rakamazi Nagy-morotva oxbow lake. Our goal was to identify the aquatic vegetation on genus-level in a study area using a multispectral UAV camera. Based on our research, we recommend using additional input datasets, such as digital surface models, spectral and texture indices, in addition to spectral bands for classification, as the appropriate combinations of these input variables can significantly improve classification accuracy.
