A new approach to satellite-derived bathymetry: the use of NDWI and ANN with bathymetry sections for reservoir mapping

open access: yesBoletim de Ciências Geodésicas
Abstract: Mapping the submerged bottom is a hampered task when traditional vessels are inserted in shallow places that pose a danger to navigation. In this sense, current research has sought optical remote sensing to obtain bathymetry estimates in larger locations in less time.

Application of Satellite-Derived Bathymetry in Hydrographic Activity of the Republic of Croatia

open access: yes, 2023
Hydrography is the branch of applied sciences that deals with the measurement and description of the physical features of oceans, seas, and coastal areas. Sea depth measurements were primarily carried out for the purposes of navigation safety, especially in shallow coastal areas.

GRDL: A New Global Reservoir Area‐Storage‐Depth Data Set Derived Through Deep Learning‐Based Bathymetry Reconstruction

open access: yesWater Resources Research
Reservoirs play a critical role in the global water cycle by regulating the flow of water from the environment into human systems. Accurate estimation of the area‐storage‐depth relationships for global reservoirs is essential for effective hydrological ...

Bathymetric truthiness : classifying valid and erroneous depths in satellite derived bathymetry with random forest

open access: yes
Recent decades have seen rapid growth in algorithms and workflows for generating bathymetry from multispectral satellite imagery, with the output typically referred to as satellite derived bathymetry (SDB).

Expected applications of Satellite Derived Bathymetry to hydrographic services.

open access: yes, 2017
The authors have been developing the technique of Satellite Derived Bathymetry( SDB) and have created trial SDBs at various waters around Japan. The trial SDB around Hateruma Island, Okinawa Pref., penetrates down to 24 m, which infers the maximum ...
