Landform mapping of Okinoshima island and sea bed of Munakata city

A comprehensive landform mapping of Okinoshima Island and the seabed of Munakata City reveals significant geological insights, contributing to the understanding of the Sacred Island of Okinoshima and Associated Sites in the Munakata Region. The study identifies a horseshoe-shaped caldera structure formed by the set of islands, with Okinoshima rising approximately 340 meters above a flat seabed. Topographic analysis shows a shallow flat table to the west and a concave area inclining eastward. Using GIS, the research integrates ground elevation maps, slope maps, relief maps, and 3D images, alongside geospatial data from GSI and JHA, to classify landforms such as crests, steep cliffs, and talus cones. The findings highlight restricted access areas while providing valuable references for understanding the island's formative processes.
