Experiment on extracting forest canopy height from Worldview-2
2011 Eighth International Conference on Fuzzy Systems and Knowledge Discovery (FSKD), 2011Taking advantage of rational polynomial coefficient (RPC) data delivered along with the very high resolution satellite (VHRS) Worldview-2 images, we proposed an easy RPC adjustment method for the commercial software ENVI to generate digital surface model (DSM) with only one ground control point (GCP). The DSM was then used to derive canopy crown height

Water availability predicts forest canopy height at the global scale
Ecology Letters, 2015AbstractThe tendency of trees to grow taller with increasing water availability is common knowledge. Yet a robust, universal relationship between the spatial distribution of water availability and forest canopy height (H) is lacking. Here, we created a global water availability map by calculating an annual budget as the difference between precipitation

A backscattering data simulation model for forest canopy based on canopy height information
2018 IEEE Radar Conference (RadarConf18), 2018The traditional backscattering data simulation models of forest canopy use uniform distribution or random distribution to simulate the vegetation distribution that are different from the real scene. To simulate the backscattering data of forest canopy realistically, a simulation method based on canopy height information is proposed.

Modeling forest canopy heights: The effects of canopy shape
Remote Sensing of Environment, 1997Abstract Three-dimensional models that represent the top-of-canopy forest height structure were developed to simulate airborne laser profiling responses along forested transects. The simulator which produced these 3-D models constructed individual tree crowns according to a tree's total height, height to first branch, crown diameter, and crown shape (

Estimation of forest canopy height by integrating multisensor data
SPIE Proceedings, 2009Forest canopy height is an important input for ecosystem and highly correlated with aboveground biomass at the landscape scale. In this paper, we make efforts to extract the maximum canopy height using GLAS waveform combination with the terrain index in sloped area where LiDAR data were present.

A forest canopy height surface model for scene simulation
SIMULATION, 1987A model of forest canopy heights can support realistic remote sensing scene simulation. The final pixel (x, y) array of canopy heights results from merging structural and statistical sub-models. The structural model considers tree crowns to be structural primitives and permits explicit specification of forest structural characteristics (crown forms ...

Forest Canopy Height Extraction in Rugged Areas With ICESat/GLAS Data
IEEE Transactions on Geoscience and Remote Sensing, 2014Geoscience Laser Altimeter System data have been widely used in forest canopy height extraction. It is still challenging over rugged areas. In this paper, we propose a forest canopy height extraction method consisting of the Savitzky-Golay filter and fitting, Sigbeg determination based on the fitting results, and slope correction for rugged areas ...

Laser altimeter canopy height profiles: methods and validation for closed-canopy, broadleaf forests
Remote Sensing of Environment, 2001Waveform-recording laser altimeter observations of vegetated landscapes provide a time-resolved measure of laser pulse backscatter energy from canopy surfaces and the underlying ground. Airborne laser altimeter waveform data was acquired using the Scanning Lidar Imager of Canopies by Echo Recovery (SLICER) for a successional sequence of four, closed ...

Uncertainty in lidar derived canopy height models in three unique forest ecosystems
2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017NEON conducts annual LiDAR flights over several ecologically unique sites within the continental United States. One of the products derived from the LiDAR acquisitions is a canopy height model (CHM), required to make inferences about vegetation structure and annual changes in growth.
