Modelling of hybrid digital elevation model / Mohd Raimi Irfan Roselan

Digital Elevation Model (DEM) are commonly produced through different surveying approaches that varied in processing techniques, cost and time. DEM is used to represent the terrain of the earth. On this century, Unnamed Aerial Vehicle (UAV) has been widely used in many surveying applications as a da...

There are two (2) types of UAV which are multi-rotor and fixed wing. Multi-rotor UAV is used as an instrument for data acquisition for this study because it has all the specification for monitoring and mapping. The DEM in the study was collected and evaluated and corrected by using the levelling elevation points observed by Global Navigation Satellite System (GNSS).
