Comparison of Tree Extraction from Intensity Drop and From Multiple Returns in ALS Data
LIDAR data Tree extraction Airborne Laser Scanner Three dimensional Intensity Drop Multiple Returns
2015/11/20
LIDAR is an application widely open as an area of study for modelling detailed topographic maps. It is generally used in airborne applications. In this study, the aim is tree extraction from a data ha...
A Comparison of Estimating Forest Canopy Height Integrating Multi-sensor data Synergy--A Case Study in Mountain Area of Three Gorges
Forest Canopy Height, Lidar Multisensor Integration Three Gorges Spatial models
2015/11/20
Forest canopy height is an important input for ecosystem and highly correlated with aboveground biomass at the landscape scale. In this paper, we make efforts to extracte the maximum canopy height usi...
A COMPARISON OF TWO DIFFERENT APPROACHES OF POINT CLOUD CLASSIFICATION BASED ON FULL-WAVEFORM LIDAR DATA
full-waveform LiDAR Decomposition Unsupervised classification point cloud, space transform EM algorithm
2012/7/24
In this paper, two different point cloud classification approaches were applied based on the full-waveform LiDAR data. At the beginning, based on the full-waveform LiDAR data, we decomposed the backsc...
Variability of Urban Aerosols over Santiago, Chile: Comparison of Surface PM10 Concentrations and Remote Sensing with Ceilometer and Lidar
Aerosols Lidar Ceilometer PM10 Santiago Chile
2012/2/28
Lidar instruments have proven useful for characterizing the structure and dynamics of aerosol layers. We compare here
the diurnal, seasonal and vertical variability of urban aerosols as described by ...
PSC:A Human-Computer Interaction System for Protein 3D Structure Comparison
Human-Computer Interaction System Protein 3D Structure Comparison
2004/12/31
Since protein 3D structures are more conserved than sequences and even functions, analyzing the protein 3D
structure is very important to the understanding of biological processes. With the accumulat...
