The shoreline is important as a baseline for national boundaries. Shoreline surveys are necessary to determine the length, area, and shape of a country and should be periodically investigated. Existing shoreline surveys were conducted based on surveying equipment such as the GNSS (Global Navigation Satellite System) and total stations and depth measurements. However, this method requires a lot of manpower and time. In this study, coastline survey was performed using high resolution image of UAV (Unmanned Aerial Vehicle). For the study, the west sea island was selected as the study area, and about 300 images were acquired and DSM (Digital Surface Model) and ortho image were obtained through data processing. The accuracy of the result was evaluated and the accuracy was confirmed to be less than 10 cm. In addition, DSM-based contour lines were created to provide basic data for determining shoreline. Shoreline surveying using UAV will greatly increase the efficiency of related work, and it will be possible to determine the shoreline by linking with tidal observations data.
