Influence of solar zenith angle and neighboring trees on the reflectance of boreal trees in multispectral aerial images (with lidar-derived crown modeling) Open
Information about forest tree species is essential for understanding and managing forest ecosystems. Aerial images and LiDAR are important complementary data sources for species classification in individual tree remote sensing. In Finland,…

Effects of Viewing Geometry on Multispectral Lidar-Based Needle-Leaved Tree Species Identification Open
Identifying tree species with remote sensing techniques, such as lidar, can improve forest management decision-making, but differences in scan angle may influence classification accuracy. The multispectral Titan lidar (Teledyne Optech Inc.…

Effect of feature standardization on reducing the requirements of field samples for individual tree species classification using ALS data Open
The objective of this study was to evaluate the effectiveness of three standardization approaches for airborne laser scanning (ALS) feature values used for individual tree species classification. This study is the first effort to assess th…

A Comparison of Three Airborne Laser Scanner Types for Species Identification of Individual Trees Open
Species identification is a critical factor for obtaining accurate forest inventories. This paper compares the same method of tree species identification (at the individual crown level) across three different types of airborne laser scanni…

Estimating the Height and Basal Area at Individual Tree and Plot Levels in Canadian Subarctic Lichen Woodlands Using Stereo WorldView-3 Images Open
Lichen woodlands (LW) are sparse forests that cover extensive areas in remote subarctic regions where warming due to climate change is fastest. They are difficult to study in situ or with airborne remote sensing due to their remoteness. We…

Discrimination of canopy gaps and non-regenerating openings in old-growth temperate deciduous forests using airborne LiDAR data Open
The use of LiDAR in the study of gap regimes has seen significant progress in recent years. Researchers have assumed that canopy gaps detected in this manner are ecologically equivalent to gaps sampled in situ by more traditional methods. …

A Generalized Lidar-Based Model for Predicting the Merchantable Volume of Balsam Fir of Sites Located along a Bioclimatic Gradient in Quebec, Canada Open
Lidar-based models rely on an optimal relationship between the field and the lidar data for accurate predictions of forest attributes. This relationship may be altered by the variability in the stand growth conditions or by the temporal di…

Modeling the Effect of the Spatial Pattern of Airborne Lidar Returns on the Prediction and the Uncertainty of Timber Merchantable Volume Open
Lidar data are regularly used to characterize forest structures. In this study, we determine the effects of three lidar attributes (density, spacing, scanning angle) on the accuracy and the uncertainty of timber merchantable volume estimat…
View article: Lidar and Multispectral Imagery Classifications of Balsam Fir Tree Status for Accurate Predictions of Merchantable Volume
Lidar and Multispectral Imagery Classifications of Balsam Fir Tree Status for Accurate Predictions of Merchantable Volume Open
Recent increases in forest diseases have produced significant mortality in boreal forests. These disturbances influence merchantable volume predictions as they affect the distribution of live and dead trees. In this study, we assessed the …

The Delphi method as an alternative to standard committee meetings to identify ecological issues for forest ecosystem-based management: A case study Open
The face-to-face committee meeting is one of the most common expert consultation methods used in forest management. However, it is also laden with disadvantages, such as potential inequity in its consideration of participant opinion and th…
