Refined Geometric Modeling of Laser Pulse Propagation in Airborne LiDAR Bathymetry

Airborne Lidar Bathymetry

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...

Forest Modeling using Airborne Lidar

Building up forest inventories for performing forest management is currently done manually through field cruises and interpretation of the aerial imagery, which is a labor-intensive task. Airborne lidar technology is capable of building a point cloud off the top surface of the ground objects. Modeling urban areas from the lidar has been successfully accomplished. However, for forest modeling, t...

The study of propagation of a femtosecond laser pulse in the breast tissue

In this paper, the evaluation of time profile of a femtosecond pulse laser propagated through biological tissues is studied. The majority of the biological tissues with a high scattering anisotropy must be considered as turbid media, that their optical responses are complicated. To study the propagation of ultra-short pulse in turbid media, the diffuse equation is used. In this study, the analy...

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 ...
