In this study, individual tree height (TH), crown base height (CBH), crown area (CA) and crown volume (CV), which were considered as essential parameters for individual stem volume and biomass estimation, were estimated by both an airborne laser scanner (ALS) and a terrestrial laser scanner (TLS). These ALSand TLS-derived tree parameters were compared because TLS has been introduced as an instr...

A nonlinear mixed-effects modeling approach was used to model the individual tree height–diameter relationship based on Chapman-Richards function for dahurian larch (Larix gmelinii. Rupr.) plantations in northeastern China. The study involved the estimation of fixed and random parameters, as well as procedures for determining random effects variance-covariance matrices to reduce the number of t...

Tree diameter at breast height (dbh) and height are the most important variables used in forest inventory and management as well as forest carbon-stock estimation. In order to identify the key stand variables that influence the tree height-dbh relationship and to develop and validate a suit of models for predicting tree height, data from 5961 tree samples aged from 6 years to 53 years and colle...

Multi-temporal sets of ERS-1/2 SAR interferometric (InSAR) phase have been evaluated at several test sites in Europe for tree height estimation. Atmospheric artefacts affected a large number of image pairs. These were generally well compensated in case of large-scale artefacts over small forests, whereas for large forests their effect could only be assessed. Hence, the amount of pairs utilizabl...

Biomass stored in young forests has enormous potential for the reduction of fossil fuel consumption. However, to ensure long-term sustainability, measurement accuracy tree height is crucial forest biomass and carbon stock monitoring, particularly forests. Precise using traditional field measurements challenging time consuming. Remote sensing (RS) methods can, however, replace field-based invent...

Accurate individual tree segmentation (ITS) is fundamental to forest management and the studies of ecosystem. Unmanned Aerial Vehicle Light Detection Ranging (UAV-LiDAR) shows advantages for ITS height estimation at stand landscape scale. However, dense deciduous forests with tightly interlocked crowns challenge performance ITS. Available LiDAR points through crown appropriate algorithm are exp...

introduction: height is an important biological human characteristic in anthropological studies and forensic medicine. in this way, forearm length (fal) can be a useful factor for the height prediction in different population. the goal of this study was to find the relation between fal and height in natives of kerman. methods: in a cross-sectional study, 150 cases including 75 males and 75 fema...
