Data set related to the single-beam bathymetry data restoration

This dataset consists of 6 regions, each of which is composed of two files: (1) single-beam bathymetric point cloud, provided in txt format; (2) DEM, provided in tif format. It is mainly used to study the method of restoring a complete DEM from single-beam bathymetric point clouds for the sparse distribution of roots, thereby achieving the representation of the seabed topography. This dataset selects 6 typical seabed terrains globally, including seamounts, trenches, and basins, etc. The terrain in each region is complex and variable, and is representative.
