Within the scope of this master's thesis, methods of SfM photogrammetry and TLS will be presented, through which three-dimensional information about the topography of Crnej Beach in the city of Rijeka will be collected. The application of UAV-SfM, hand-held SfM, and TLS technologies in the coastal area will be demonstrated, with two separate surveys conducted with a 4-month interval. Utilizing software packages such as CloudCompare, Agisoft Metashape, FARO Scene, AutoCAD, and QGIS, the thesis thoroughly explains the processes of generating, processing, and analyzing point clouds, DEMs, orthophoto images, cross-sections, and height changes in models. Furthermore, the thesis describes the georeferencing procedure for the generated point clouds, which is crucial for their integration and further analysis. Moreover, a detailed comparison of cross-sections generated from point clouds and DEM is carried out, encompassing an investigation of cross-sections obtained through the use of UAV-SfM, TLS, and hand-held SfM methods. The research also addresses the examination of the accuracy of the applied surveying methods via UAV-SfM and TLS, along with the analysis of height changes over time detected by UAV-SfM and hand-held SfM methods, aimed at illustrating the potential for precise material volume determination. Finally, the advantages and limitations of UAV-SfM, hand-held SfM, and TLS methods are considered, emphasizing the significance of 3D models in improving the design process and efficient management of coastal areas.
