DERIVATION OF FOREST INVENTORY PARAMETERS FOR CARBON ESTIMATION USING TERRESTRIAL LIDAR
Terrestrial LiDAR Point Cloud Data Tropical Rain Forest Inventory Parameters Above Ground Carbon Estimation
2016/11/30
This research was conducted to derive forest sample plot inventory parameters from terrestrial LiDAR (T-LiDAR) for estimating above ground biomass (AGB)/carbon stocks in primary tropical rain forest. ...
AUTOMATIC THICKNESS AND VOLUME ESTIMATION OF SPRAYED CONCRETE ON ANCHORED RETAINING WALLS FROM TERRESTRIAL LIDAR DATA
LiDAR point cloud retaining wall rock bolts shotcrete feature extraction volume calculation
2016/11/11
When ground conditions are weak, particularly in free formed tunnel linings or retaining walls, sprayed concrete can be applied on the exposed surfaces immediately after excavation for shotcreting roc...

tree height old-growth forest canopy structure canopy projection terrestrial lidar
2015/11/10
Terrestrial lidar measurements with the Leica HDS 4500 laserscanner (Imager 5003 from Z+F) were executed in a structurally highly diverse, at least 200-year-old natural 11-species forest with typical ...
3D Scan of Ornamental Column (huabiao) Using Terrestrial LiDAR and Hand-held Imager
3D Scan Ornamental Column Huabiao
2015/9/14
In ancient China, Huabiao was a type of ornamental column used to decorate important buildings. We carried out 3D scan of a
Huabiao located in Peking University, China. This Huabiao was built no late...
INTEGRATING TERRESTRIAL LIDAR WITH POINT CLOUDS CREATED FROM UNMANNED AERIAL VEHICLE IMAGERY
Unmanned Aerial Vehicle Terrestrial LiDAR Point Cloud Data Fusion
