Global 1-km Coastal Bathymetry from Sentinel-2 Wave Inversion using the Satellite-to-Shores (S2hores) Toolbox [PDF]

Scientific Data
Reliable and up-to-date coastal bathymetry remains scarce for many of the world’s shorelines, limiting progress in coastal monitoring, hazard assessment, and numerical modeling.

A VGGNet-Based Method for Refined Bathymetry from Satellite Altimetry to Reduce Errors

Remote Sensing, 2022
Only approximately 20% of the global seafloor topography has been finely modeled. The rest either lacks data or its data are not accurate enough to meet practical requirements.

Study on the optimization of ship survey line placement based on multibeam bathymetry

Advances in Computer Signals and Systems, 2023
: The multibeam bathymetry technology measures water depth strip by transmitting multiple beams through transducer, which is more efficient and accurate than the traditional bathymetry methods. In this paper, we focus on the measurement of the bathymetry
