FULLY AUTOMATED GIS-BASED INDIVIDUAL TREE CROWN DELINEATION BASED ON CURVATURE VALUES FROM A LIDAR DERIVED CANOPY HEIGHT MODEL IN A CONIFEROUS PLANTATION
Crown Delineation Canopy Height Model (CHM) Local Maxima Curvature Slope Thiessen Polygons
2016/11/30
The generation of high resolution canopy height model (CHM) from LiDAR makes it possible to delineate individual tree crown by means of a fully-automated method using the CHM’s curvature through its s...
A DECIDIOUS-CONIFEROUS SINGLE TREE CLASSIFICATION AND INTERNAL STRUCTURE DERIVATION USING AIRBORNE LIDAR DATA
LiDAR species classification geometrical analysis bole derivation branch derivation
2016/2/29
This project has two main purposes; the first is to perform deciduous-coniferous classification for 65 trees by using the leaf-on single
flight LiDAR data. It was done by looking at the geometrical ...
DECIDUOUS-CONIFEROUS TREE CLASSIFICATION USING DIFFERENCE BETWEEN FIRST AND LAST PULSE LASER SIGNATURES
Leaf-off First-last pulse Species identification Airborne laser scanners
2015/11/10
In this paper, a deciduous-coniferous tree classification mechanism is proposed, tested and analyzed using solely laser scanner data.The data were acquired under leaf-off conditions by Toposys II syst...
ASSESSMENT OF SUB-CANOPY STRUCTURE IN A COMPLEX CONIFEROUS FOREST
LiDAR understorey vegetation vegetation cover
2015/11/10
LiDAR technology emits narrow beams of laser light that are able to exploit gaps in the forest canopy and detect sub-canopy surfaces. In this study, we explore the potential of airborne LiDAR to quant...
ANGULAR UNMIXING OF PHOTOSYNTHETIC AND NON-PHOTOSYNTHETIC VEGETATION WITHIN A CONIFEROUS FOREST USING CHRIS-PROBA
Non-Photosynthetic Vegetation spectral unmixing FLIGHT
2015/9/8
Estimating forest variables, such as photosynthetic light use efficiency, from satellite reflectance data requires understanding the
contribution of photosynthetic vegetation (PV) and nonphotosynthet...
RETRIEVAL OF CONIFEROUS CANOPY CHLOROPHYLL CONTENT FROM HIGH SPATIAL RESOLUTION HYPERSPECTRAL DATA
Remote Sensing Hyperspectral High Resolution
2015/9/8
The discrete Anisotropic Radiative Transfer (DART) model, coupled with an adjusted version of the PROSPECT model, was used to
retrieve total chlorophyll content (Cab) of a complex Norway spruce (Pice...
Analysis of coniferous species to identify and distinguish juvenile and mature wood
differentiation methods k-means algorithm forest management
2015/5/5
We conducted to describe methods used to differentiate the zones of juvenile and mature wood in
stems of coniferous species and to present the importance of good identification of the shares of both...
PROGRESS IN LIDAR ALTIMETER REMOTE SENSING OF STAND STRUCTURE IN DECIDUOUS AND CONIFEROUS FORESTS USING SLICER DATA
Lidar forest structure biomass canopy
2014/12/22
Large footprint, waveform sampling lidar altimetry has a number of benefits over traditional, small footprint, single return laser altimetry for the remote sensing of forest structure. Nevertheless, i...
It is difficulties for the computer simulation method to study radiation regime at large-scale. Simplified coniferous model was investigated in the present study. It makes the computer simulation meth...
