The Historical Complexity of Tree Height Growth Dynamic Associated with Climate Change in Western North America
height growth site index global climate change species range species characteristics species ecological amplitude geographic locations western North America
2023/12/1
The effect of climate on tree growth has received increased interest in the context of climate change. However, most studies have been limited geographically and with respect to species. Here, sixteen...
Unmanned?aerial?vehicles (UAV)-based canopy height modeling under leaf-on and leaf-off conditions for determining tree height and crown diameter (case study: Hyrcanian mixed?forest)
canopy height model digital elevation model forest inventory unmanned aerial vehicles (UAVs) tree crown architecture
2023/12/1
Tree height and crown diameter are two common individual tree attributes that can be estimated from unmanned aerial vehicle (UAV) images thanks to photogrammetry and structure from motion. This resear...
Using Tree Height, Crown Area and Stand-Level Parameters to Estimate Tree Diameter, Volume, and Biomass of Pinus radiata, Eucalyptus globulus and Eucalyptus nitens
radiata pine blue gum shinning gum diameter-height allometry crown diameter stem volume above-ground biomass growth and yield modeling remote sensing
2023/11/22
Accurate estimates of tree diameter, height, volume, and biomass are important for numerous economic and ecological applications. In this study, we report exponential equations to predict tree DBH (cm...
IMPACTS OF TREE HEIGHT-DBH ALLOMETRY ON LIDAR-BASED TREE ABOVEGROUND BIOMASS MODELING
tree aboveground biomass lidar allometric equations simulation regression
2016/11/30
Lidar has been widely used in tree aboveground biomass (AGB) estimation at plot or stand levels. Lidar-based AGB models are usually constructed with the ground AGB reference as the response variable a...

2015/12/29
Light Detection And Ranging (LiDAR), is a system of laser detection and distance measurement installed on aircraft or satellites. Because of its high angular resolution, high range resolution and anti...
Comparison of linear mixed effects model and generalized model of the tree height-diameter relationship
height function mean height Michailoff function Norway spruce mean diameter uniform height curve
2015/11/26
Models of height curves generated using a linear mixed effects model and generalized model were compared. Both tested models were also compared with local models of height curves, which were fitted us...
TREE HEIGHT ESTIMATION METHODS FOR TERRESTRIAL LASER SCANNING IN A FOREST RESERVE
Terrestrial Laser scanning Forestry Photogrammetry Modelling Single tree
2015/11/10
A terrestrial laser scanning survey has been performed on a forest reserve site. This paper represents the processing of the dataset. Two new methods have been developed for tree positioning, which is...
Our previous studies using airborne lidar data have shown that the tree height indices derived from the GLAS and
LVIS waveforms were highly correlated. The quartile waveform energy heights derived fr...
TREE-HEIGHT MEASURING CHARACTERISTICS OF URBAN FORESTS BY LIDAR DATA DIFFERENT IN RESOLUTION
LIDAR Urban Vegetation Multiresolution Measurement Accuracy Comparison
2015/7/29
Urban forests are important as valuable green resources to give moisture and tranquillity of mind in our living, requiring an efficient
control of forest increase/decrease and growth rate. In this s...
Generalized additive models as an alternative approach to the modelling of the tree height-diameter relationship
nonparametric method Norway spruce Petterson function
2015/7/2
Generalized additive models were tested using three types of smoothing functions as an alternative for
modelling the height curve. The models were produced for 23 forest stands of Norway spruce (Pic...
