摘要: 随着海洋综合调查工作的不断深入,海岛(礁)作为海洋中的重要要素,其完整的水上水下地形数据是了解岛礁和规划岛礁的基础。本文首先通过多波束测深系统配合三维激光获取海岛礁水上水下一体化地形数据;然后结合山东省东部一座典型海岛进行试验,重点探讨基于多波束测深系统在岛礁地形数据获取中的应用;最后进行精度评定,并对数据成果进行展示。试验结果表明,利用高低潮差采用船载测量系统配合无人船测量系统,可以一次性获取完全覆盖岛礁水陆交界区域,数据完整且精度高。水上水下全覆盖数据成果能够真实地反映岛礁及周边范围的地形情况,为规划建设和生态监测提供数据支撑。

Abstract: With the deepening of marine comprehensive survey, islands (reefs) as an important element of the ocean, its complete surface and underwater terrain data is the basis of understanding and planning islands and reefs. The multi-beam sounding system combined with 3D laser is used to obtain the integrated topographic data of islands and reefs above and below water. The experiment is carried out in combination with a typical island in eastern Shandong province, focusing on the application of the multi-beam sounding system in the topographic data acquisition of islands and reefs, the accuracy assessment is carried out, and the data results are displayed. The results of the study area show that the ship-borne measurement system combined with the unmanned ship measurement system can obtain the land and water interface area of the reef completely at one time by using the high-low tidal range, and the data is complete and high precision. The full coverage data results can truly reflect the topography of islands and reefs and their surrounding areas, which provide the data support for planning and construction and ecological monitoring.

Key words: island (reef) topographic survey, multi-beam sounding system, accuracy evaluation, shipborne measurement system, unmanned ship measurement system
