Integration of UAV-derived digital elevation model and GNSS for orthometric height determination in urban mapping

Accurate orthometric height information is critical for a variety of urban geospatial applications, including cadastral mapping, infrastructure development, and flood risk assessment. Traditional techniques such as differential leveling, while precise, are labour-intensive, time-consuming, and ofte...
