Lessons Learnt from the High Resolution Uas Photogrammetric Survey of a Historic Urban Area: UNESCO Site of Sabbioneta

A high-resolution UAS photogrammetric survey of Sabbioneta, a UNESCO World Heritage Site in northern Italy, demonstrates the efficacy of unmanned aerial systems (UAS) for capturing detailed 3D models and orthophotos of historic urban areas. The study achieved a pixel resolution of 1 cm, highlighting the potential of UAS technology to overcome challenges posed by complex historic environments that may hinder traditional surveying methods. The approach involved using DJI Matrice 300 RTK with a high-precision GNSS Mobile Station and Agisoft Metashape for image processing, adhering to European UAS flight regulations. The resulting dense point cloud is suitable for future segmentation and urban analysis, offering valuable insights for smart city development and preservation efforts.
