Calibrated Full-Waveform Airborne Laser Scanning for 3D Object Segmentation

Remote Sensing, 2014
Segmentation of urban features is considered a major research challenge in the fields of photogrammetry and remote sensing. However, the dense datasets now readily available through airborne laser scanning (ALS) offer increased potential for 3D object ...

Developing Allometric Equations for Teak Plantations Located in the Coastal Region of Ecuador from Terrestrial Laser Scanning Data [PDF]

, 2019
Traditional studies aimed at developing allometric models to estimate dry above-ground biomass (AGB) and other tree-level variables, such as tree stem commercial volume (TSCV) or tree stem volume (TSV), usually involves cutting down the trees.

Retrieval Algorithms for Road Surface Modelling Using Laser-Based Mobile Mapping

Sensors, 2008
Automated processing of the data provided by a laser-based mobile mapping system will be a necessity due to the huge amount of data produced. In the future, vehiclebased laser scanning, here called mobile mapping, should see considerable use for road ...

Evaluating the Performance of Photogrammetric Products Using Fixed-Wing UAV Imagery over a Mixed Conifer-Broadleaf Forest: Comparison with Airborne Laser Scanning

Remote Sensing, 2018
Unmanned aerial vehicles (UAVs) and digital photogrammetric techniques are two recent advances in remote sensing (RS) technology that are emerging as alternatives to high-cost airborne laser scanning (ALS) data sources.

Tree species classification in Norway from airborne hyperspectral and airborne laser scanning data

European Journal of Remote Sensing, 2018
This article compares four new automatic methods to discriminate between spruce, pine and birch, which are the dominating tree species in Norwegian forests. Airborne laser scanning and hyperspectral data were used.

Point Cloud Data Mining With HD Map Priors for Making Synthetic Forest Datasets

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Airbornelaser scanning has proven to be an indispensable tool in surveying outdoor areas due to its efficient land coverage and unimpeded access to difficult-to-reach areas. The spatial information in 3-D point clouds, the data produced in airborne laser

An Evolutionary Approach towards Clustering Airborne Laser Scanning Data

, 2012
In land surveying, the generation of maps was greatly simplified with the introduction of orthophotos and at a later stage with airborne LiDAR laser scanning systems. While the original purpose of LiDAR systems was to determine the altitude of ground elevations, newer full wave systems provide additional information that can be used on classifying the ...
