Coconut Creek (Florida), ISSN 0749-0208.Coastal areas adjacent to the sea are vulnerable to disasters every year due to repeated damage caused by typhoon-induced tsunamis, seawater flooding, and erosion. As such, a method for comprehensively managing coastal facilities and areas vulnerable to danger, based on underwater, aerial, and underground information included in the three-dimensional (3D) grid system was prepared, which can serve as an objective and scientific data source for the decision-making involved in effective coastal management. To this end, the concept and roles of the 3D spatial grid system are introduced in this study. In addition, through 3D data production and visualization utilizing this method and considering the characteristics of coastal areas, a method for comprehensive management of coastal areas through the 3D spatial grid system is proposed.
