An Introduction to Coastal Zone Mapping with Airborne Lidar: the Shoals System
Recent advancements in lidar sensors now allow for near-synoptic, regional-scale mapping of the coastal zone. One such sensor is the US Army Corps of Engineers SHOALS system. SHOALS is unique in that it is the only lidar sensor, worldwide, that simultaneously collects bathymetry and adjacent topography. Because of SHOALS’ rapid collection rate, data density, and system accuracy, it is now cost ...
متن کاملPerformance Assessment of High Resolution Airborne Full Waveform LiDAR for Shallow River Bathymetry
We evaluate the performance of full waveform LiDAR decomposition algorithms with a high-resolution single band airborne LiDAR bathymetry system in shallow rivers. A continuous wavelet transformation (CWT) is proposed and applied in two fluvial environments, and the results are compared to existing echo retrieval methods. LiDAR water depths are also compared to independent field measurements. In...
متن کاملLiDAR Bathymetry for Nautical Charting
Safety Of Life at Sea (SOLAS) is the overarching principle for all offshore operations and one of the major contributing factors to SOLAS is quality navigational charts that are comprehensive and adhere to International Hydrographic Organisation (IHO) established standards of accuracy. However, a chart is only as good as the data that is used to compile it and one of the more challenging areas ...
متن کاملA State of Art on Airborne Lidar Application in Hydrology and Oceanography: a Comprehensive Overview
Nowadays, lidar has been accepted as one of the important sensors providing accurate and dense 3D point cloud from earth surface terrain and water bathymetry. The basic idea of using lidar stems from the problem of measuring water depth without direct contacting with the water body or without any instrument mounted on the water surface in shallow regions. Bathymetric lidar that uses two differe...
متن کاملLe développement de LiDAR satellitaire multifonctions. Analyse exploratoire du potentiel de capteurs LiDAR pour le suivi altimétrique et bathymétrique des surfaces en eau continentales et côtières
Possessing accurate, spatial and current data on the water levels and the depths are necessary for anticipation and better management of coastal and continental waters. Among the remote sensing techniques to monitor the water bathymetry and altimetry, the LIDAR appears as an adapted and promising technique, already proven on airborne platforms, because of its potential accuracy, spatial resolut...
