Beach profile, total station, UAVAbstract
The advancement of technology has allowed the application of Unmanned Aerial Vehicle (UAV) for beach surveying to be used instead of theodolite method. This is still a debatable issue whether UAV can completely replace the theodolite method for future research. The studied area at Seberang Takir, Kuala Nerus is recognized as a critical erosion site and beach nourishment activity has been undertaken here on an approximately five year cycle. This study aims to show the potential of UAV application for coastal research. The results show that the elevation data of drone extracted from Digital Elevation Model (DEM) are match equivalent to the total station elevation data within 0.03 m. The beach profile graph of the drone and total station show significant differences in the steeper area. This study shows that the UAV image technique using a drone holds the potential for monitoring and quantifying the beach changes to levels of accuracy and precision that can be compared to the theodolite method. UAV has a big potential for beach monitoring and it is encouraged to be applied for further understanding of how and when they can be most useful.
