Understanding satellite-derived bathymetry using Sentinel 2 imagery and spatial prediction models [PDF]

, 2019
Optical satellite data is an efficient and complementary method to hydrographic surveys for deriving bathymetry in shallow coastal waters. Empirical approaches (in particular, the models of Stumpf and Lyzenga) provide a practical methodology to derive ...

Evaluating ACOMP, FLAASH and QUAC on Worldview-3 for satellite derived bathymetry (SDB) in shallow water

Geodesy and Cartography, 2020
Bathymetry map is instrumental for monitoring marine ecosystem and supporting marine transportation. Optical satellite imagery has been widely utilised as an alternative method to derive bathymetry map in shallow water.

Seamount resolution in satellite‐derived bathymetry [PDF]

Geochemistry, Geophysics, Geosystems, 2005
I compare satellite‐derived global relief data on 13 seamounts in the northeast Pacific Ocean to echosounder‐derived multibeam values from the Gulf of Alaska Seamount Expeditions and the West Coast Seamounts and Ridges Multibeam Surveys for peak height, latitude, longitude, and midsection area.

A comparison of Landsat 8, RapidEye and Pleiades products for improving empirical predictions of satellite-derived bathymetry [PDF]

, 2019
Satellite derived bathymetry (SDB) enables rapid mapping of large coastal areas through measurement of optical penetration of the water column. The resolution of bathymetric mapping and achievable horizontal and vertical accuracies vary but generally ...

Evaluation of the Accuracy of Bathymetry on the Nearshore Coastlines of Western Korea from Satellite Altimetry, Multi-Beam, and Airborne Bathymetric LiDAR

Sensors, 2018
Bathymetric mapping is traditionally implemented using shipborne single-beam, multi-beam, and side-scan sonar sensors. Procuring bathymetric data near coastlines using shipborne sensors is difficult, however, this type of data is important for maritime ...

An Improved Gridded Bathymetric Data Set and Tidal Model for the Maldives Archipelago

Earth and Space Science, 2021
The Maldives faces a unique range of environmental challenges. While the country is almost entirely dependent upon oceanic resources with more than 99% of the area covered by ocean, the absence of a suitable bathymetric map of the seafloor of the ...

Pan-European Satellite-Derived Coastal Bathymetry—Review, User Needs and Future Services

Frontiers in Marine Science, 2021
Low-lying coastal zones are home to around 10% of the world’s population and to many megacities. Coastal zones are largely vulnerable to the dynamics of natural and human-induced changes.

Bathymetry mapping with empirical bathymetry method based on sentinel application platform case study: Bawean Island, Central Java [PDF]

BIO Web of Conferences
Bathymetry information is an important requirement for the marine and fisheries sector in Indonesia. However, the acquisition of information is done in the traditional way, namely surveys using single/multibeam echosounder devices carried by ships.
