Likelihood Ratio Statistic for Inferring the Uncertainty of Satellite Derived Bathymetry
2021 11th Workshop on Hyperspectral Imaging and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2021We consider the study of performing likelihood-based inference in Lee's radiative transfer semi-analytical model. This model is widely used for the inversion of bathymetric products in coastal areas. We perform assessment of uncertainty on retrieved bathymetry in terms of hypothesis testing.

Satellite-Derived Bathymetry Using Deep Convolutional Neural Network
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020Our goal is to develop technique for assessing bathymetry maps, which show the topography of the floors of water-bodies, using satellite or aerial imagery. The advent of deep neural networks has enabled the use of new techniques in analysing and creating depth maps from high resolution satellite images.

Satellite-derived bathymetry integrating spatial and spectral information of multispectral images
Applied Optics, 2023As a significant and cost-effective method of obtaining shallow seabed topography, satellite derived bathymetry (SDB) can acquire a wide range of shallow sea depth by integrating a small quantity ofin-situwater depth data. This method is a beneficial addition to traditional bathymetric topography.

Mapping Multidecadal Morphological Variability Via Satellite Derived Bathymetries
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018This paper outlines a novel approach to calibrating satellite derived relative depth surfaces generated using the ratio transform algorithm first proposed by Stumpf et al. The method utilizes raster image equal interval classification to generate depth classes and to identify both the upper and lower limits of sensitivity to the depth signal within the

Physics-based satellite-derived bathymetry
Coastal and inland shallow-water environments are increasingly exposed to climate-change-related impacts such as sea-level rise, coastal erosion and ecosystem degradation. Reliable numerical hydrodynamic and morphological models are essential for assessing these impacts and supporting coastal adaptation strategies [1].Annika Klein, C. Gabriel David

Global Coastal Satellite-Derived Bathymetry
Coastal zones are home to about 40% of the world's population and include key infrastructure and ecosystems. These regions are crucial for economic activities like maritime transport or the deployment of offshore renewable energy, are vital for human settlement and contain unique habitats.Mona Reithmeier +3 more

Satellite-derived bathymetry to improve bathymetric map of Indonesia
Sixth International Symposium on LAPAN-IPB Satellite, 2019Satellite imagery along with image processing techniques are essential tools for bathymetry retrieval since they are relatively inexpensive in term of time and budget in comparison to the conventional bathymetry survey. Approximately, 1126 bathymetric maps in various scales were produced by Badan Informasi Geospasial (BIG) covering Indonesia’s oceans ...

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.

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
