Land surveying with UAV photogrammetry and LiDAR for optimal building planning

Accurate land surveys are fundamental for optimal building planning, as topography bridges architecture and landscape. This paper proposes a Digital Feature Model (DFM) that integrates UAV photogrammetry and LiDAR data to optimize terrain mapping. UAV photogrammetry provides high-accuracy mapping of textured anthropic surfaces, while LiDAR excels in penetrating vegetation-covered areas. By segmenting and fusing datasets from both sensors, the DFM enhances accuracy across diverse terrain conditions. In a built environment case study, 233 measured points representing ground, vegetation, and anthropic features were analyzed to validate the methodology. The DFM achieved a vertical RMSE of 0.075 m, outperforming…
