Changes in the seafloor relief are particularly noticeable in shallow waterbodies (at depths
up to several metres), where they are of significance for human safety and environmental …

Autonomous technologies are increasingly used in various areas of science. The use of
unmanned vehicles for hydrographic surveys in shallow coastal areas requires accurate …

The aim of this research is to propose a new solution to assist sailors in safe navigation on
inland shallow waters by using Augmented and Virtual Reality. Despite continuous progress …

Hydrographic surveys, in accordance with the International Hydrographic Organization (IHO)
S-44 standard, can be carried out in the following five orders: Exclusive, Special, 1a, 1b and …

Bathymetric measurements in waters shallower than 1 m are necessary to monitor seafloor
relief changes in the coastal zone. This is especially important for ensuring the safety of …

Due to the complex hydrology and narrow channels of inland rivers, ship collision accidents
occur frequently. The traditional collision-avoidance algorithms are often aimed at sea …

This paper presents a method for integrating data acquired by unmanned surface vehicles
and unmanned aerial vehicles. The aim of this work was to create a uniform bathymetric …

The Gray Wolf (GWO) algorithm aims to address the path planning problem of multiple
UAVs, and the scene setting is mainly to avoid threats, meet the constraints of UAVs …

Shallow water bathymetry is of great significance in understanding, managing, and
protecting coastal ecological environments. Many studies have shown that both empirical …

A unique drone-based system for underwater mapping (bathymetry) was developed at the
University of Florida. The system, called the “Bathy-drone”, comprises a drone that drags, via …
