Abstract:

In recent years, Unmanned Aerial Vehicle (UAV) photogrammetric methods, have been successfully applied in many fields, including surveying engineering, due to low-cost of UAV systems, uncomplicated image processing, and short time taking for generating map productions. However, the accuracy of these mapping products for different types of terrains using the UAV photogrammetric methods is still poorly understood. The main objective of this study was to assess the accuracy of Digital Surface Model (DSM) and orthophoto derived from a UAV photogrammetric method at relative flat terrain. Accordingly, influencing of the fly height, number, density, and distribution of ground control points (GCPs) to the final map productions were analyzed and assessed. An experimental case study was carried at an flat area of the Duc Thang ward, the North Tu Liem district (Hanoi city), using Phantom 3 Professional equipped the RGB Sony EXMOR cameras.
