UAV is emerging to become a common tool in geoscience field as it is usable across different field to cover a large-scale area with minimal cost. A low-cost UAV with low-altitude platform is advantageous as it is not affected by cloud cover and easily operable which allows frequent flight of the same area at low-cost. This is applicable in monitoring effects of coastal erosion and shoreline changes. Coastal erosion is recognized as a permanent loss of land and habitat along the shoreline resulting in changes of the coast. The shoreline is highly vulnerable to erosion and flooding that can spawn negative impact on wellbeing of human, environment and ecosystem altogether. Hence, it is important to monitor shoreline changes by identifying the rate of erosion and accretion to quantify the losses of land due to climate change. This research suggests the usage of DJI Phantom 3 Pro to monitor the shoreline changes physically at Pantai Jeram. Sub nadir aerial images were taken from the UAV and flew alongshore at above ground level of 70 m. The research was conducted at different 2 months (June and September) in 2017 to observe the shoreline changes during different monsoon periods. The result shows apparent changes of the shoreline in the west coast of Malaysia produced at high-resolution due to the images taken by the UAV at low-altitude which allows the analysis of the shoreline changes to be intricate. In Pantai Jeram, the result of 2-months observation shows noticeable changes in erosion and accretion. The research shows that UAV is applicable in monitoring shoreline changes along the coastal region which can be useful to assist the authority in making decision on enforcing nature conservation strategy to the affected site.
