In less than two decades, UASs (unmanned aerial systems) have revolutionized the field of
hydrology, bridging the gap between traditional satellite observations and ground-based …

The water depth bias of LiDAR point cloud data has to be corrected. The previous models,
which used the fixed parameters for an entire water area, cannot efficiently correct the bias …

Airborne LiDAR bathymetry (ALB) has proven to be an effective technology for shallow water
mapping. To collect data with a high point density, a lightweight dual-wavelength LiDAR …

We present the sensor concept and first performance and accuracy assessment results of a
novel lightweight topo-bathymetric laser scanner designed for integration on Unmanned …

Résumé The history of using optical methods for hydrographic applications dates back to the
mid of the last century. Since these early days, both passive and active techniques have …

Although aerial image-based bathymetric mapping can provide, unlike acoustic or LiDAR
(Light Detection and Ranging) sensors, both water depth and visual information, water …

Besides airborne laser bathymetry and multimedia photogrammetry, spectrally derived
bathymetry provides a third optical method for deriving water depths. In this paper, we …

The accurate classification and 3D mapping of benthic habitats in coastal ecosystems are
vital for developing management strategies for these valuable shallow water environments …

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 very shallow marine basin of Puck Lagoon in the southern Baltic Sea, on the Northern
coast of Poland, hosts valuable benthic habitats and cultural heritage sites. These include …
