Satellite-Derived Bathymetry for Selected Shallow Maltese Coastal Zones
Applied Sciences, 2023 Bathymetric information has become essential to help maintain and operate coastal zones. Traditional in situ bathymetry mapping using echo sounders is inefficient in shallow waters and operates at a high logistical cost.

Satellite-Derived Bathymetry for Improving Canadian Hydrographic Service Charts [PDF]
ISPRS International Journal of Geo-Information, 2018 Approximately 1000 Canadian Hydrographic Service (CHS) charts cover Canada’s oceans and navigable waters. Many charts use information collected with techniques that predate the more advanced technologies available to Hydrographic Offices (HOs ...

A COMBINED COLOR AND WAVE-BASED APPROACH TO SATELLITE DERIVED BATHYMETRY USING DEEP LEARNING [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 Knowledge of the evolution of the littoral zone over time is paramount for coastal science and coastal zone management. However, traditional bathymetric surveys using echo-sounding techniques are unsuitable for large-scale applications due to a variety ...

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.
