Abstract

This invention discloses a method, device, medium, and product for visualizing the spatial distribution of marine sediments. The method includes: collecting sediment samples from various spatial sampling points in a target sea area to obtain sediment grain size composition data; calculating the sediment energy intensity at each point and determining an optimized sediment classification threshold set for each point by combining it with a standard sediment classification threshold set; using this optimized threshold set and grain size composition data to determine the sediment substrate type at each sampling point; constructing a spatial triangular network based on all sampling points, and interpolating classification boundary points on the triangular network by combining its grain size data, substrate type, and standard threshold set; dividing the sea area into polygonal regions corresponding to each substrate type based on the boundary points, performing automated color filling and type labeling, and finally generating a spatial distribution map of marine sediments. The technical solution of this invention can achieve comprehensive and accurate classification of marine sediments and complete the visualization mapping of their spatial distribution.
