Remote Sensing, 2023 The new spaceborne photon-counting lidar, i.e., ICESat-2, has shown great advantages in obtaining nearshore bathymetry at a global scale. The forward-scattering effect in the water column is one of the main error sources in airborne lidar bathymetry (ALB)

AIRBORNE LIDAR BATHYMETRY APPLIED TO COASTAL HYDRODYNAMIC PROCESSES [PDF]
Coastal Engineering Proceedings, 2011 In this study, the possibility to get sedimentological (density, compaction) and hydrodynamical (suspended sediment concentration, turbulence) information from ALB surveys is demonstrated. ALB laser reflectance was found to be higher on the lee-side and on the crest of the ripple bedform than in the trough and on the stoss-side.

A Combined Approach for Retrieving Bathymetry from Aerial Stereo RGB Imagery
Remote Sensing, 2022 Shallow water bathymetry is critical in understanding and managing marine ecosystems. Bathymetric inversion models using airborne/satellite multispectral data are an efficient way to retrieve shallow bathymetry due to the affordable cost of airborne ...

ACCURACY OF MEASURING THE BOTTOM OF A POND BY AIRBORNE LIDAR BATHYMETRY (ALB) [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Abstract. Airborne Lidar Bathymetry (ALB) is a technology for characterizing the depths of shallow-water bodies in relatively transparent waters from an airborne platform using a scanning and pulsed light beam. A bathymetric LiDAR usually uses wo laser pulses: one is a near-infrared (NIR) laser pulse for land topography and the other is a green laser ...

Clear Waters, Stronger Depths: Advancing Bathymetric Lidar Through Community Practices [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesThe science of mapping beneath the water's surface with lasers is no longer novel, but its relevance has never been greater. Over the past decade, bathymetric lidar has evolved from a niche tool into a diverse ecosystem of sensors and operators, tailored

Refined Geometric Modeling of Laser Pulse Propagation in Airborne LiDAR Bathymetry [PDF]
PFG – Journal of Photogrammetry, Remote Sensing and Geoinformation Science, 2021 AbstractTo achieve a geometrically accurate representation of the water bottom, airborne LiDAR bathymetry (ALB) requires the correction of the raw 3D point coordinates due to refraction at the air–water interface, different signal velocity in air and water, and further propagation induced effects.

Application of airborne LiDAR bathymetry in Norway
, 2022 New technologies in remote sensing provide opportunities for effectively sampling information on topography and bathymetry for large areas. With Airborne LiDAR Bathymetry (ALB) terrain and also the river bottom (bathymetry) can be measured with high accuracy.
