[1] Data from spaceborne light detection and ranging (lidar) opens the possibility to map forest vertical structure globally. We present a wall-to-wall, global map of canopy height at 1-km spatial resolution, using 2005 data from the Geoscience Laser Altimeter System (GLAS) aboard ICESat (Ice, Cloud, and land Elevation Satellite). A challenge in the use of GLAS data for global vegetation studies is the sparse coverage of lidar shots (mean = 121 data points/degree2 for the L3C campaign). However… 

Investigating the agreement between global canopy height maps and airborne Lidar derived height estimates over Canada

Carbon storage in forest aboveground biomass is a critical, yet difficult, component of the global carbon cycle to estimate. Canopy height, a key indicator of carbon storage, can be estimated from

Regional scale rain-forest height mapping using regression-kriging of spaceborne and airborne LiDAR data: Application on French Guiana

Canopy heights extracted from both airborne and spaceborne LiDAR, were first extrapolated from available environmental data to propose a forest canopy height map with good precision and high spatial resolution.

Continental-Scale Canopy Height Modeling by Integrating National, Spaceborne, and Airborne LiDAR Data

Abstract Canopy height estimates are widely used in forest biomass and carbon assessment modeling applications with the goal of mitigating climate change through the modification of forest

Exploring the Relationship between Forest Canopy Height and Canopy Density from Spaceborne LiDAR Observations

A simple allometric model is evaluated that relates global forest canopy height (RH100) and canopy density measurements to explain spatial patterns of forest structural properties and has potential application in frameworks that target the retrieval of above-ground biomass.

This study derived a relationship between the weighted mean tree height derived from airborne lidar data and the predictedmean tree height within the GLAS footprints; the resulting equation explained 82.8% of variance.

Regionalization of an Existing Global Forest Canopy Height Model for Forests of the Southern United States

It was concluded that the characterization of the agreement of a selected G CHM with local data, followed by the recalibration of the existing GCHM to the local region, is both viable and essential for future GCHMs in studies conducted at large scales.

Fine-resolution forest tree height estimation across the Sierra Nevada through the integration of spaceborne LiDAR, airborne LiDAR, and optical imagery

This study presented a method to map wall-to-wall forest tree height (defined as Lorey's height) across the Sierra Nevada at 70-m resolution by fusing multi-source datasets, including over 1600 in situ tree height measurements and over 1600 km2 airborne light detection and ranging (LiDAR) data.

Mapping Forest Canopy Height Across Large Areas by Upscaling ALS Estimates with Freely Available Satellite Data

An easily adopted method for generating a continuous map of canopy height at a 30 m resolution is demonstrated over 2.9 million hectares of highly heterogeneous forest in Victoria, Australia, suggesting there is no upper limit to model scalability.
