Satellite-Derived Bathymetry using Adaptive Geographically Weighted Regression Model
Marine Geodesy, 2016ABSTRACTThe common practice adopted in previous attempts on Satellite-Derived Bathymetry (SDB) has been to calibrate a single set of coefficients using global regression model. In this study we propose an Adaptive-Geographically Weighted Regression (A-GWR) model that takes into account local factors in determining the regression coefficients.

SATELLITE DERIVED BATHYMETRY – LOW COST SURVEY SYSTEMS [PDF]
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

Deriving three dimensional reservoir bathymetry from multi-satellite datasets
Remote Sensing of Environment, 2018Abstract We evaluate different techniques that rebuild reservoir bathymetry by combining multi-satellite imagery of surface water elevation and extent. Digital elevation models (DEMs) are processed in two distinct ways in order to determine 3-D reservoir bathymetry. They are defined as (a) linear extrapolation and (b) linear interpolation.

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 ...

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 bathymetries through high space-time resolution videos
Coastal bathymetric datasets are critical to improve our understanding of morphodynamic processes in the coastal area, as well as for decision-making on future adaptation measures. Originally designed for analyzing snapshots and time-exposure images from coastal video monitoring stations installed on buildings near the coastline, video techniques have ...Candela Marco-Peretó +5 more

Water column optical properties infuence in satellite-derived bathymetry
Hydrographische NachrichtenSatellite-derived bathymetry (SDB) has become increasingly recognised for its effectiveness in acquiring bathymetric data in recent decades. This method heavily relies on water properties to estimate depths accurately, assuming minimal backscatter from the water column and focusing mainly on seabed backscatter.

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.
