The Role of Improved Ground Positioning and Forest Structural Complexity When Performing Forest Inventory Using Airborne Laser Scanning

Remote Sensing, 2020
The level of spatial co-registration between airborne laser scanning (ALS) and ground data can determine the goodness of the statistical inference used in forest inventories.

Another dimension from LiDAR – Obtaining foliage density from full waveform data [PDF]

, 2011
LiDAR tells the user where surfaces are, not what they are. In this study we investigate the potential for waveform LiDAR to provide more information on the nature of the returns over forestry. Waveform LiDAR was acquired for ten Pinus radiata plots in a

Airborne photogrammetry and LIDAR for DSM extraction and 3D change detection over an urban area : a comparative study [PDF]

, 2013
A digital surface model (DSM) extracted from stereoscopic aerial images, acquired in March 2000, is compared with a DSM derived from airborne light detection and ranging (lidar) data collected in July 2009.

Predicting stand age in managed forests using National Forest Inventory field data and airborne laser scanning

Forest Ecosystems, 2020
Background The aim of this study was to construct a nationwide stand age model by using National Forest Inventory (NFI) data and nationwide airborne laser scanning (ALS) data. In plantation forestry, age is usually known.

Glacier changes in the Bavarian Alps from 1989/90 to 2006/07 [PDF]

, 2008
The five glaciers in Bavaria which today cover a total area of less than one square kilometer were frequently monitored by geodetic methods from the mid of the 20th century. In this paper, the record is extended by new surveys in 1999 and 2006.

Forest structural diversity characterization in Mediterranean landscapes affected by fires using Airborne Laser Scanning data

GIScience & Remote Sensing, 2020
Forest fires can change forest structure and composition, and low-density Airborne Laser Scanning (ALS) can be a valuable tool for evaluating post-fire vegetation response.

Area-based vs tree-centric approaches to mapping forest carbon in Southeast Asian forests from airborne laser scanning data

, 2017
Tropical forests are a key component of the global carbon cycle, and mapping their carbon density is essential for understanding human influences on climate and for ecosystem-service-based payments for forest protection.
