Shallow Water Bathymetry Derived by Machine Learning and Multitemporal Satellite Images
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Shallow water bathymetry is essential information for coastal science and nautical navigation. In this study, a satellite derived bathymetry (SDB) map, considered suitable for shallow water, was created using random forests (RF) and multi-temporal satellite images from Google Earth Engine.

Improving Satellite-Derived Bathymetry Estimation With a Joint Classification–Regression Model
IEEE Geoscience and Remote Sensing LettersEmerging deep learning methods for satellite-derived bathymetry (SDB), in which water depth is estimated using satellite band reflectance values, typically treat the problem as either classification or regression tasks, which can underperform ...

Testing Approaches and Sensors for Satellite-Derived Bathymetry in Nunavut
2020Nearshore bathymetry in the Canadian Arctic is poorly surveyed, but is vital knowledge for coastal communities that rely on marine transportation for resources and development. Nautical charts currently available are often outdated and surveying by traditional methods is both time consuming and expensive.

SATELLITE DERIVED BATHYMETRY – LOW COST SURVEY SYSTEMS [PDF]
, 2017 Satellite Derived Bathymetry (SDB) uses satellite or other remote multispectral imagery for depth determination. Recent advances in satellite technology (spectral, radiometric, temporal and spatial resolution improved) have increased the potential of this method as a source of hydrographic data. This method became widely used in the last few years. SDB
