Discrete return lidar-based prediction of leaf area index in two conifer forests

Simulating the impact of discrete-return lidar system and survey characteristics over young conifer and broadleaf forests

Influence of Vegetation Structure on Lidar-derived Canopy Height and Fractional Cover in Forested Riparian Buffers During Leaf-Off and Leaf-On Conditions

Estimates of canopy height (H) and fractional canopy cover (FC) derived from lidar data collected during leaf-on and leaf-off conditions are compared with field measurements from 80 forested riparian buffer plots. The purpose is to determine if existing lidar data flown in leaf-off conditions for applications such as terrain mapping can effectively estimate forested riparian buffer H and FC wit...

Going Undercover: Mapping Woodland Understorey from Leaf-on and Leaf-off Lidar Data

An understorey model is created for an area of broadleaf, deciduous woodland in eastern England using airborne LiDAR data from winter 2003 (leaf-off conditions) and summer 2005 (leaf-on). The woodland is ancient, semi-natural broadleaf and has a heterogeneous structure, with a mostly closed canopy overstorey and a patchy understorey layer beneath. In places, particularly in the centre of the st...

Lidar Remote Sensing: Mapping British Columbia’s Forests with Lasers

The most common type of lidar sensors operating within British Columbia are small-footprint, discrete return systems that record two to five returns for each emitted laser pulse. The distance between the lidar sensor and a target is estimated by multiplying the speed of light by half the amount of elapsed time between pulse emission and return detection. As the laser signal is reflected back to...

A Comparison of Remote Sensing Methods for Estimating Above-Ground Carbon Biomass at a Wetland Restoration Area in the Southeastern Coastal Plain by

Developing accurate but inexpensive methods for estimating above-ground carbon biomass is an important technical challenge that must be overcome before a carbon offset market can be successfully implemented. Previous studies have shown that full-waveform LiDAR (light detection and ranging) is well suited for modeling above-ground biomass in mature forests; however, there has been little previou...
