Abstract
In recent years, local governments have been promoting tourism by making great use of regional characteristics. Kyotango City in Kyoto Prefecture makes use of the beautiful sea of Japan to focus on attracting visitors for leisure and sightseeing. However, since there are 15 beaches in Kyotango City, we cannot easily grasp the appealing point of each, much less provide them. In this paper, to grasp water depth changes in Kyotango's beaches, we first describe how to gather the data needed to visualize changes in water depth at Kyotango's beaches and to generate 3D water depth map based on the gathered data. We next demonstrate that the singular value decomposition of matrices composed of gathered data can be used to clarify the complexity of water depth changes and the similarity among them.
