IMPROVEMENTS IN LIDAR BATHYMETRY DATA ANALYSIS

Airborne Lidar Bathymetry

LiDAR 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 ...

A Matlab Geodetic Software for Processing Airborne Lidar Bathymetry Data

The ability to build three-dimensional models through technologies based on satellite navigation systems GNSS and the continuous development of new sensors, as Airborne Laser Scanning Hydrography (ALH), data acquisition methods and 3D multi-resolution representations, have contributed significantly to the digital 3D documentation, mapping, preservation and representation of landscapes and herit...

River bathymetry from conventional LiDAR using water surface returns

LiDAR–based DEMs are almost essential when it comes to high resolution floodplain modelling. Conventional LiDAR does not penetrate water bodies and additional bathymetric measurements are necessary to complete any parts of a DEM which were under water at the time of the LiDAR sortie. Bathymetric data collection is time-consuming, expensive and it requires careful processing to correctly interpo...

Performance Improvements for Lidar-Based Visual Odometry

Performance Improvements for Lidar-Based Visual Odometry Hang Dong Master of Applied Science Graduate Department of Aerospace Science and Engineering University of Toronto 2013 Recent studies have demonstrated that images constructed from lidar reflectance information exhibit superior robustness to lighting changes. However, due to the scanning nature of the lidar and assumptions made in previo...
