水陆空一体化技术在长江水下地形测绘中的应用

Application of water,land and air integration technology in underwater topographic mapping of the Yangtze River

针对河流难以及时获取地理信息数据的问题,通过单波束技术、多波束技术、激光雷达技术的融合,可以快速实现地水下地形测绘。依托长江水下地形测绘项目,证明了这几种技术在获取水下地形数据方面的可行性,并系统地介绍了水下测绘的完整流程,为大规模开展类似项目提供参考依据。

Addressing the issues which are difficult to be obtained timely the geographic information for rivers,the underwater terrain surveying tasks have been quickly accomplished by integrating single beam technology,multi beam technology,and LiDAR technology.Based on the underwater terrain measurement task of the Nantong section of the Yangtze River,the feasibility of these technologies in obtaining underwater terrain data has been proven,and the complete process of underwater surveying has been systematically introduced through this project.And it provides reference basis for large-scale similar projects.
