Supporting Long-Term Archaeological Research in Southern Romania Chalcolithic Sites Using Multi-Platform UAV Mapping

Spatial data play a crucial role in archaeological research, and orthophotos, digital elevation models, 3D models are frequently used for the mapping, documentation, monitoring of sites. Thanks to availability compact low-cost uncrewed airborne vehicles, use UAV-based photogrammetry matured this field over past two decades. More recently, systems also available that allow recording thermal data, multispectral laser scanning. In article, various platforms sensors applied at Chalcolithic sites Mosti?tea Basin Danube Valley (Southern Romania). By analysing performance resulting insight is given into selection appropriate system right application. This analysis requires thorough knowledge acquisition processing, as well. As both scanning typically result very large amounts special focus required on storage publication data. Hence, objective article provide full overview aspects mapping. Based conclusions drawn it stated can with similar geometrical properties when parameters appropriately set. On one hand, ALS-based outperforms photogrammetric terms operational time area covered. other conventional provides flexibility might be low-altitude flights, or emergency Furthermore, ALS sensor only representation topography, still obtain true colour false composites surface. Lastly, variety such pre- post-rendered raster point clouds, implementation multiple methods online Various client-side server-side solutions presented make researchers.
