Airborne lidar bathymetry is an efficient technique for measuring the bottom of shallow water bodies. A characteristical feature of lidar bathymetry beam propagation is given by scattering and absorption effects in the water column, both leading to a loss of received signal intensity.

Use of Airborne LIDAR Bathymetry for Coastal Hydrographic Surveying: The French Experience
Journal of Coastal Research, 2011Abstract Starting in 2005, the French Naval Hydrographic and Oceanographic Office (Service Hydrographique et Oceanographique de la Marine [SHOM]) and the French National Geographic Institute (Institut Geographique National [IGN]) began conducting a series of coastal surveys using airborne light detection and ranging (LIDAR) bathymetry (ALB) and ...

Waveform decomposition and feature extraction of airborne LiDAR bathymetry
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021To develop the data mining capability of airborne LiDAR bathymetry (ALB) waveform information, the waveform decomposition and feature extraction algorithm of airborne LiDAR bathymetry is proposed in this paper. This method uses the “separate” and “combine” two-step optimized waveform decomposition algorithm to decompose the bottom contribution waveform

Registration of Airborne LiDAR Bathymetry and Multibeam Echo Sounder Point Clouds
IEEE Geoscience and Remote Sensing Letters, 2022Airborne light detection and ranging (LiDAR) bathymetry (ALB) and multibeam echo sounder (MBES) are both active remote sensing technologies that are complementary in terms of survey scope. The registration of ALB and MBES data can provide complete overwater and underwater geoinformation on a measurement target.

Abstract Through an extensive literature review the results of previous lidar investigations in Australia, Canada, Sweden, the U.S.A. and West Germany have been evaluated. Based on these findings estimates are given for the anticipated depth capability, measurement accuracy and operational constraints for a laser system in U.K. waters. Consideration is

Advances and perspectives in bathymetry by airborne lidar
SPIE Proceedings, 2015In this paper, the history of the airborne lidar and the development stages of the technology are reviewed. The basic principle of airborne lidar and the method of processing point-cloud data were discussed. At present, single point laser scanning method is widely used in bathymetric survey.

Feasibility study for airborne fluorescence/reflectivity lidar bathymetry
SPIE Proceedings, 2012There is a demand from the authorities to have good maps of the coastal environment for their exploitation and preservation of the coastal areas. The goal for environmental mapping and monitoring is to differentiate between vegetation and non-vegetated bottoms and, if possible, to differentiate between species.

Assessing the ability of airborne LiDAR to map river bathymetry
Earth Surface Processes and Landforms, 2007AbstractAirborne bathymetric LiDAR was collected for 220 river kilometres in the Yakima and Trinity River Basins in the USA. Concomitant with the aerial data collection, ground surveys of the river bed were performed in both basins. We assess the quality of the bathymetric LiDAR survey from the perspective of its application toward creating accurate ...
