Integration of Terrestrial and Airborne Lidar Data for System Calibration
The ever improving capabilities of the direct geo-referencing technology is having a positive impact on the widespread adoption of LiDAR systems for the acquisition of dense and accurate surface models over extended areas. LiDAR systems can quickly provide accurate surface models with a dense set of irregular points, surpassing the quality of those derived from other techniques, such as manual ...
متن کاملRadiometric Calibration of a Dual-Wavelength, Full-Waveform Terrestrial Lidar
Radiometric calibration of the Dual-Wavelength Echidna(®) Lidar (DWEL), a full-waveform terrestrial laser scanner with two simultaneously-pulsing infrared lasers at 1064 nm and 1548 nm, provides accurate dual-wavelength apparent reflectance (ρ(app)), a physically-defined value that is related to the radiative and structural characteristics of scanned targets and independent of range and instrum...
متن کاملModeling Semiarid Low-Height Vegetation with Airborne LiDAR
Low-height vegetation, common in semiarid regions, is difficult to characterize with airborne LiDAR (light detection and ranging) due to the similarities, in time and space, of the point returns of vegetation and ground. Other complications may occur due to the lowheight vegetation structural characteristics and the effects of terrain slope. This research is focused on modeling methods and erro...
متن کاملDelineation of Vegetation and Building Polygons from Full- Waveform Airborne Lidar Data Using Opals Software
Full-waveform LiDAR is an active remote sensing technique that provides the scattering properties of the targets i.e. amplitude and echo width (EW) in addition to 3D point clouds. The amplitude provides information on the target's reflectance and the EW is a measure for the range variation of scatterers within the laser footprint contributing to a single echo and is, therefore, an indicator for...
متن کاملAirborne LiDAR and Terrestrial Laser Scanning Derived Vegetation Obstruction Factors for Visibility Models
Research presented here explores the feasibility of leveraging vegetation data derived from airborne light detection and ranging (LiDAR) and terrestrial laser scanning (TLS) for visibility modeling. Using LiDAR and TLS datasets of a lodgepole pine (Pinus contorta) dominant ecosystem, tree canopy and trunk obstructions were isolated relevant to a discrete visibility beam in a short-range line-of...
