Using Hyperspectral Frame Images from Unmanned Airborne Vehicle for Detailed Measurement of Boreal Forest 3D Structure
(Iop Publishing Ltd, 2016-01-01)
Objective of this work was to investigate the feasibility of using multi-image matching and information extracted from image classification to improve strategies in generation of point clouds of 3D forest scene. Image data ...
Assessing Biodiversity in Boreal Forests with UAV-Based Photogrammetric Point Clouds and Hyperspectral Imaging
(Mdpi, 2018-02-01)
Forests are the most diverse terrestrial ecosystems and their biological diversity includes trees, but also other plants, animals, and micro-organisms. One-third of the forested land is in boreal zone; therefore, changes ...
UAV-based photogrammetric point clouds and hyperspectral imaging for mapping biodiversity indicators in boreal forests
(2017-10-19)
Biodiversity is commonly referred to as species diversity but in forest ecosystems variability in structural and functional characteristics can also be treated as measures of biodiversity. Small unmanned aerial vehicles ...

Effect of Clearcutting Operations on the Survival Rate of a Small Mammal
(Cross Mark, 2015)
Clearcutting is a common timber harvesting technique that represents a significant and abrupt change in habitat conditions for wildlife living in industrial forests. Most research on this type of impact has focused on ...

Climate and atmospheric circulation related to frost-ring formation in Picea mariana trees from the Boreal Plains, Central Canada
(Elsevier, 2020-05)
Earlier spring and earlier onset of growth, as a consequence of climate change, may expose trees and crops to increased risk of exposure to frost damage. In this study, we compare the frequency of frost rings in three ...
Estimating canopy fuel load with hemispherical photographs: A rapid method for opportunistic fuel documentation with smartphones
(British Ecological Society, 2021-08)
Canopy fuel load (CFL) affects wildfire intensity and is a critical input for fire behaviour models; however, measuring CFL in the field is time-consuming and costly. Until recently, hemispherical photographs have been ...
