I-Construction 2.0, which aims to improve productivity by utilizing 3D data throughout the entire construction and production process of port construction, is being promoted, and the spread of multi-beam sounding, which can obtain detailed topographical information over a wide area, is expected. On the other hand, it is difficult to perform simple sounding using manned vessels, and the data processing method carried out by experienced engineers based on their experience has the problem that the labor required for analysis processing increases as the amount of data increases compared to single-beam sounding. To solve this problem, this study verified the application of multi-beam sounding using an autonomous small vessel and automated data processing in the field. Specifically, it was demonstrated that by combining an autonomous small vessel with automatic processing such as the CUBE algorithm, it was possible to obtain highly accurate water depth values while significantly reducing the labor required for surveying and data analysis, and that construction management was made more efficient.
