Abstract
Timely understanding of sedimentation changes in the Shenzhen River,the boundary river be-tween Shenzhen and Hong Kong,is crucial for accumulating relevant foundational data and for the ef-fective operation and management of the river.Relying on the Shenzhen River Topographic measurement project with the aim of acquiring topographic and geomorphic data of the Shenzhen River,and based on the analysis of the shortcomings of traditional surveying methods in tidal river mapping,the project employed cutting-edge technologies such as three-dimensional laser scanning,unmanned boat measure-ment,oblique photogrammetry,etc.,to conduct comprehensive measurements of the Shenzhen River chan-nel.The synergistic application of various cutting-edge surveying techniques had greatly improved op-erational efficiency,effectively ensuring the accuracy of results and the integrity of data acquisi-tion,laying the foundation for subsequent result mapping.The multi-source water depth data acquisi-tion technology could be applied in similar tidal river cases,demonstrating significant benefits.关键词
