Autor: Thomas R. Fox, Valerie A. Thomas, Matthew Sumnall, Randolph H. Wynne
Publikováno v: ISPRS Journal of Photogrammetry and Remote Sensing. 133:186-200
The objective of the current study was to develop methods for estimating the height and horizontal coverage of the forest understorey using airborne Lidar data in three managed pine plantation forest typical of the south eastern USA. The current proj

Analysis of a lidar voxel-derived vertical profile at the plot and individual tree scales for the estimation of forest canopy layer characteristics
Autor: Alicia Peduzzi, Thomas R. Fox, Matthew Sumnall, Randolph H. Wynne, Valerie A. Thomas
Publikováno v: International Journal of Remote Sensing. 37:2653-2681
The goal of the current study was to develop methods of estimating the height of vertical components within plantation coniferous forest using airborne discrete multiple return lidar. In the summer of 2008, airborne lidar and field data were acquired

Assessing the transferability of statistical predictive models for leaf area index between two airborne discrete return LiDAR sensor designs within multiple intensely managed Loblolly pine forest locations in the south-eastern USA
Autor: Alicia Peduzzi, Randolph H. Wynne, Valerie A. Thomas, Bruce D. Cook, Matthew Sumnall, Thomas R. Fox
Publikováno v: Remote Sensing of Environment. 176:308-319
Leaf area is an important forest structural variable which serves as the primary means of mass and energy exchange within vegetated ecosystems. The objective of the current study was to determine if leaf area index (LAI) could be estimated accurately

Estimating leaf area index at multiple heights within the understorey component of Loblolly pine forests from airborne discrete-return lidar
Autor: Christine E. Blinn, Thomas R. Fox, Valerie A. Thomas, Randolph H. Wynne, Matthew Sumnall
Publikováno v: International Journal of Remote Sensing. 37:78-99
Airborne discrete-return light detection and ranging lidar can be used to estimate leaf area index LAI with relatively high accuracy. This capacity was explored with regard to assessing the capability of estimating LAI at different heights at the plo

Comparison of small-footprint discrete return and full waveform airborne lidar data for estimating multiple forest variables
Autor: Ross A. Hill, Shelley A. Hinsley, Matthew Sumnall
The quantification of forest ecosystems is important for a variety of purposes, including the assessment of wildlife habitat, nutrient cycles, timber yield and fire propagation. This research assesses the estimation of forest structure, composition a
